Can't Import Fixture Library

I tried importing my patch file from V2 to V3 but I have a few custom fixture files so it cancels the import. A warning came up saying I need to import another fixture library but when I go to import another fixture library it won’t let me open anything. I can’t select certain files, folders or the whole fixture library to import.

Any help is appreciated.

Picture is attached.

Use the import fixture function in the fixture editor rather than the import library. You can then import each of the .fix2 files into your user folder.
