I absolutely depend on Media Tags for my student researchers to store and retrieve media on our site at sge.lclark.edu. I have seen occasional oddities, however, with this taxonomy apparently conflicting with another, and now have time to look into it: it appears that when a name is duplicated in the wp_terms table, it generates an error, resulting in a suffix attached to the slug. In our case, we use a tag for each student research project, and the exact same string in Media Tags for their media. This works fine about 95% of the time, but occasionally generates errors when I'm editing a tag or media tag. The reason seems to be that my post tags and media tags share the same ID those 95% of the time, but when their IDs are different (i.e., there are >1 instances of the same name in the wp_terms table), the error occurs.
Would sure appreciate assistance! Thanks.
