Without knowing more, it sounds like something is corrupted with the filters file, as it seems to all work fine for me. Please try going to C:\Users\<your username>\AppData\Local\Packages\41730Zubersoft.MobileSheets_ys1c8ct2g6ypr\LocalState, delete user_filters.xml and restart MobileSheets. You can then try creating your filters again, save them, restart MobileSheets and verify it works like you would expect when you load those filters.
