I am at 99% on Sapienza and it says I still have 1 more location to discover to unlock the achievement, however, there are no icons on the map legend revealing where the locations left to be discovered are. I have the same issue on Whittleton Creek, I would really like to have 100% on all maps. These are the last two I have left, and only need 1 location each, is this a bug? or are there secret locations on Sapienza and Whittleton Creek that dont’ show up on the map?
Yes there is a bug with discovery challenge on multiple locations. If you don’t have an undiscovered icon on any location then don’t bother with it until it’s fixed, just a waste of time.

Just for gather up all alike threads in one place.
Maybe there’s more, found only these
If someone still unaware, this bugfix is officially confirmed for February update
