Achievement "map room" is not completed.

I can't complete this achievement, even though I've already filled in all the pixels. I tried with both maps, the normal one and the localizer and it still doesn't work, I installed a texture to see if there are any missing pixels and I didn't find any. My world has achievements activated, as I managed to do one recently on 04/18/2024
