Outdated Baked Mesh Maps?

When I pull up my Resources updater, it keeps showing my baked maps as outdated. I tried deleting the maps from my Asset library and refreshed the resources updater, and it gets rid of the error. However, every time I reload the project, they just pop back up.

Also, why are there 3 copies of each of my baked maps in my asset library?

One last thing... what is the "4" overlaid on each map referring to?

Any help would be much appreciated!
