[BUG?] MIDI Mix/Stacked not playing 1st bar on loop

Is anyone having this issue?

When you record MIDI in Mix/Stacked mode, it doesn’t play the 1st half of the 1st bar of the previously recorded track on the 1st loop pass.

E.G. record a HH part on the 1st pass. When it loops, the 1st half of the 1st bar of the HH you just recorded doesnt play. On the next pass it does.

Can anyone reproduce this?

Anyone?
