Hidden tile (Hide plane) function not working

Describe the Bug
Was loading up a board that I made back initially when TaleSpire was in Beta and have been adding onto it over the patches. I load onto it today and buildings arent disappearing to see inside them on creatures I have control of, and the green tab on the side when I slide it up and down does nothing to hide the tiles.

To Reproduce
Steps to reproduce the behavior:

No idea how it happened, but loaded onto it and every time I load onto it this happens.
