Recorder trig out of sync with playback

I noticed sometimes a recorder trig on Flex Machine is out of sync with a playback on the same track after manual arming a track.

On a recording preview page I can see a playback slider is re-triggered once at the beginning and since then a recording and playback sliders are out of sync.

Removing and adding a triggers is a workaround in most of the time.

Anyone seen that?
