The entire S1 (prologue) episode should be deleted and the only entry (by Vagrant - fid 193340) moved to T2 (Curtain Raiser).
I watched it and it's the same trailer as those under T1. I guess somebody added it without watching other entries.
As of different lengths (6 vs. 7 min), actual length is 6:24, so T1 has more accurate length.
