New object matte "offset" the selection in time often

Hi, your object matte upgrade of rotobrush is fantastic, but I am facing lot of strange behavior, often with error message and sometimes with AE crash..
One of the most frequent bug I experienced is the offset of selected matte in time - like the object tracking is frame or two behind the video. Sometimes it happened in the middle of tracking, sometimes (with the same footage) it happened from the begining.. And sometimes it is all OK..
As I wrote, this is the most frequent bug I meet.. Footage is 25fps progressive prores 100%scale fullHD. Comp is also 25fps FullHD
Here is link to my onedrive - screenrecording of AE with this behavior..
