Freeze mode moves Loop OUT marker - Why ?

Hey there,

I have a question about the Freeze mode plus loop mode activated...

When I play a simple loop in the track deck, the Loop IN and Loop OUT markers are set properly (blue arrows). 

Then I activate the Freeze mode (so far all is still fine...), but when triggering/playing a random slice, the Loop OUT marker is moved slightly (see screenshot) "off grid"... (red arrow)

(Snap+Quant are active)

Why is the Loop OUT marker moved at all (bug?) ?

I'm not sure why this happens. Does anyone have any hints on how this can be fixed?

Thanks a lot,

(on Traktor Pro 4 / Mac M1 Max / S8)
