See this thread.

Basically, if you edit FFF files with exiftool, due to the weird way those files are written, the Phocus program may not be able to load the files anymore. 

As long as you're aware of the problems that can follow, you can force the editing of the files by adding the -m (ignoreMinorErrors) option.
