Im having some issues aswell with this. My finds and scans and mapping dont pick up for most of the times. And flightlog misses out of a lot of places even if i go really slow and make sure that the updater runs a full circle or two. And my jumps go back and fourth even if i go in a straight line..
Bodies/systmems i been first to discover and map sometimes dont show up in Elite dangerous either, I can go back and look at them and it says i mapped them, but my name dont show up on either mapped of first to find. I found sytems untoched but dont get a bonus for first to find/map, I do however get fist to find/map bonus on systmes i sure wasnt fist on..
So i guess there is something really broken in the game with exploration that perhaps effect EDSM to. Yesterday i got to a system that had a lot of the DW2 fleet passing trough yet there was bodies undiscovered and unmapped Yet i was able to get first discover and and first to map in game. But acording to EDSM someone else has the tags? And it say i neither scanned or mapped the bodies?
And also badges that i should recive i dont get. I found a scoopable star and was the fist one to do so with that , but didnt get the badge..
I have made sure to stay long in systems for the updater to work its magic but it will just not work sometimes. I have had similar exprience in both PG, and solo mode..
