parts missing from customfolders

[Railroadnut]

I have two custom folders. When I use manage parts, all parts are listed in the folders. When I look at parts in the schematic layout window, the folders are listed but there are no parts shown. This has just happened. Parts were visible before.

After opening the program several times and bringing in different files, I guess the library finally rebuilt itself. Everything shows up now. I have no idea how or why it finally reloaded the data.

Spoke too soon. The parts are again missing from the folders. I uninstalled PCB123, reinstalled, and reopened board. Still mising. Anybody know a way to merge files? I have a custom & custom2 file. I would prefer to have it all one. One file was created on my work PC and the other on my home PC. I loaded them both on my laptop to try to get all parts.
