...probably a bug. OH NOES CLICKBAIT

Can you tell what's wrong?

Looks like an extreme runaway greenhouse effect. Seen plenty of rocky ice worlds with that effect around G class stars and up. Never round a M class though.

Unless the body was a lot closer to the star in the past or it collided with something, it's gotta be a Stella Forge issue.

Because the previous readers have already given you hints on where to look? It's not like it's a ground-breaking lore discovery, just a fun little bug-hunt.

Well, I'd say "sure it has ice, ice of things like granite"... except granite has long since melted by 2000K. Maybe we can say it has the ice of tungsten?

At 37,000 atmospheres pressure, water ice would melt at about 120 degrees C (about 400 K). So whatever "ice" it is, it isn't water. Which would be surprising, given the 100% water atmosphere.

There are a number of different forms of water ice,this is probably ice VII which can be compressed under extreme pressure and turn into ice.

At Z and also at Sandia’s nearby STAR (Shock Thermodynamic Applied Research) gas gun facility, thin water samples were compressed to pressures of 50,000-120,000 atmospheres in less than 100 nanoseconds. Under such pressures, water appears to transform to ice VII, a phase of water first discovered by Nobel laureate Percy Bridgman in the 1930s. The compressed water appeared to solidify into ice within a few nanoseconds.

However even ordinary water can freeze at extreme pressures;

However, the behavior of pure water under high pressure remained a mystery.
Sandia instruments observed the unnucleated water becoming rapidly opaque — a sign of ice formation in which water and ice coexist — as pressure increased. At the 70,000 atmosphere mark and thereafter, the water became clear, a sign that the container now held entirely ice.

“Apparently it’s virtually impossible to keep water from freezing at pressures beyond 70,000 atmospheres,” Dolan says.

So no, entirely plausible.

About the ice: the description says "these worlds have a small metal core and thick rocky mantle with a crust of very deep ice". So I don't think you need to be concerned about how any kind of ice can exist on the surface.
Speaking of which, at a planet this light, and atmospheric pressure this high, the atmosphere itself must be very thin. Then there's the fact that it's made up entirely of water: such extreme conditions will magnify any inaccuracies in the model which FD might be using to determine the outcome. Also, while I haven't verified this yet, I'm still fairly certain that this planet would be losing its atmosphere rapidly. (Not necessarily a bug: nobody said that everything we see that has been generated by the Forge is stable.)

Titan has a thicker atmosphere than earth and this planet is more massive than Titan. This planet is also similar to Mercury (actually slightly more massive than mercury) and Mercury has a magnetic field. So, if it has a magnetic field, it wouldn't need to lose as much of its atmosphere.

So this planet could sustain a large atmosphere and a magnetic field for added protection. And since the atmosphere is already water, any atmosphere it loses would be replenished by the ice on the surface.

Oh, I actually misread the mass on the screenshot. Still, that looks interesting, I think I'll take a more detailed look at it later.
I wasn't thinking of atmospheric escape due to solar winds: rather, thermal escape, and perhaps hydrodynamic, although unlikely. However, earlier in the planet's history it might have occurred.
I know it's highly unlikely to ever happen, but it would be great to see histories in the Stellar Forge, a debug output of how the body in question came to be.
