Alembic Cache import skip every 3 frames

Hi, guys.
I´m trying to undestand why is this happening.

When import "geometry cache ( experimental ) " animation plays with interval of 3 frames.

Step to Reproduce

1- Import “geometry cache ( experimental )”

2 - Play simulate, pause, and play everyframe.

3 - Animation plays: in frames 1 - 4 - 7 - 10 - etc.

Animations plays normally in Maya

Thanks in advance.

Oh, and “sketelal” type, plays everyframe normally, but mesh dissapears when i get close more than 3 meters or so to the camera …

Are these bugs?..
