There is something wrong with mine as when you hover it doesn’t even show you an expected wait nor has an inspector ever visited this zooThere's nothing wrong in your game, just your patience level. It greys out like that in all my zoos for a period of time; there is a time gap between when the last visit of the inspector was and when you find out when the next one is. That's what the button looks like in that period. Just let time advance until you find out when the next inspection will be.
Even then, it stays grayed out until the inspector actually arrives, but mousing over it gives a tooltip that says when he is coming, as seen in the image below:

I don't recall the frequency of inspections in that particular scenario, but I do know that in some of them there are 2-3 game years, maybe even more, between inspections. Fast forward time if that's all you have left to accomplish.

I'm on this scenario now and like all my other scenarios with inspector requirements, I have had no problems. Those with the issue may want to send their game file so that they can see if the problem is due to the zoo data rather than the game itself.
I actually completed the 4.0 rating when I completed the silver requirement. And now that I am right at the end needing the animals to all have 5 stars, the inspector is now down as visiting in 24 months. This coincides with an almost perfect visit the time before with only 1 mixed habitat being given 4 stars. As I have been suspecting, the time between visits may be connected to the results of the previous visit.
