10 man Raid Frames and the Raid Leader

[Tassius]

Last night, I was forming a 10 man ulduar run for the guild, and one of my guildies informed me that I was about to 11 people into the raid. At a glance, I only saw 9 frames, but after looking closer I noticed my frame was missing, and we did have a full group. I used the /nui raidsort command to see if that would bring up my frame, but didn't. Is there some way to fix this, or is it just a bug? I'm using the 5.03.01 version from a few days ago, and when I join a raid, I see all 10 frames. This quirk seems to only show up if I'm leader and forming the raid.

Thanks!
