I would be guessing that the layer attribute numbers are different in the file that the attributes were created in and your file.
The only way to know for sure would be to compare the 2 files.
You may have the same layer names, but if they are different attribute numbers and those numbers aren't in your file, then the favourite layers will appear as "missing".
Archicad really doesn't care about the attribute names, it is the attribute number that Archicad refers to.
The easiest way to fix it if you like your current layer set-up, is unfortunately to go through and edit all of the favourites.
You can select multiple favourites at the same time and edit just the layer - nothing else will be affected.
