Multiple genre tags

Recently, Dsub for Android updated, and I noticed that the genre listing has dozens of multiple genres listed, sometimes for one album. I use Mediamonkey to tag my files from Discogs, so it does the releases in the proper format, by separating the tags with a semi-colon. Subsonic / Dsub used to only list the very first genre. For example, if the album was tagged as "Abstract; IDM; Experimental", only "Abstract" would show up, but recently, I've been seeing the behavior I captured in a screenshot. The author of Dsub says his app has nothing to do with that. Has anyone seen this and know what I could do to fix it? Thanks.
