T-posing means the chosen animation does not exist (or file corrupted?). May be it can mean the animation ends too early?
Try replacing on row 47 for file \DialogScenes\C6\M3\D1\DialogScene.xdb
<AnimName>idle01</AnimName>
with
<AnimName>idle00</AnimName>
and see if it fixes that.
btw what does ActorAnimationIndex do exactly?
