Tagging / metadata help

I’ve been trying Audiofinder on demo and it is amazing except for one thing. If I tag a file in Audiofinder, and then move it to another location, the tag is lost. The tag field in Audiofinder does not seem to hard write into the tag field of the file itself (I can check this if I look at the file in Finder).

This seems like a major flaw so I suspect I’m doing something wrong. But as I regularly re-organise my files and folders, this makes Audiofinder almost unusable for me. I’ve searched and searched for a similar topic but found nothing.

Would be grateful if someone could help.
