arcade games arent updating after switching to big box mode

[Former user]

hello ,

Today i added to my arcade library 3 new roms to be used with another version of mame than the rest of my collection. I tested it after including it on my list, but after i switch to bigbox , the games disappeared for some reason. Not only that one of the games was a copy of and old broken rom which i updated to a working one and changed the version of mame to use on that specific rom. but switching to bigbox or just closing launch box just undos this and brings back the old rom.
