Parameter names missing in Digital Performer automation

Hi, I’ve got an odd bug reported by a customer. It apparently only happens in the Audio Unit, not the VST. Parameter names are missing in Digital Performer 9.5.1 in automation, all he gets is “setting 1, setting 2, setting, 3 etc” in the drop-down list instead of the parameter names. I don’t know or have DP or have any way of testing this, so I was wondering if anybody here knows what’s happening?
