Question about logs

So I’m a feral OT for my guild, I cat dps a lot and off tank/MT some other fights. The question I had is in regarded to my supremus logs. I only talk on that fight, but Warcraft logs still shows me as cat and ranks my best dps as cat dps, so my parse is always super low on that fight. This has happened on a few others as well. Any help or insight into this issue would be greatly appreciated Note that I don’t go into cat form at all on supremus
