In fact it seems to always be the same numbers after the dots: X.874275/X
And my animation plays a bit weird. I have a 8 frames walk animation which starts at frame 2 and ends at frame 9, except it starts playing at 1.874275, so I briefly see the first frame before the actual walk cycle. It happened right after launching the app and loading the model. Oddly enough, it only happens with one model.
EDIT: I changed the starting frame to 3, then put it back to 2, and the issue disappeared.
