I have an idea what might be causing this. MUSICHI might be trying to tag this file with two genres (Dance and Hip-Hop) using the ID3v1 numeric codes for these (03 and 07) separated by a NUL character that is being displayed as a dot in the message.

This format is valid for ID3v2.4 but not for ID3v2.3. If your tags are currently in ID3v2.3 format, can you convert them to ID3v2.4 (perhaps try just one file first as a test) and see if this solves the problem?
