rekordbox dj and sampler issue

Hello. I need some help. I just moved from Traktor to Rekordbox DJ. One thing which i cannot get to work is the sync of the samplerloop with the master track. As long as the tempo is within + and - 2% it sounds ok, but as soon as i go beyond that base tempo of the drumloop it starts glitching a the end of the loop. Is doesn't matter if i make the sampler the master or the slave. In Traktor going far beyond the basetempo of the drumloop wasn't an issue.

Of course ik have looked at the drumloop, but as said, when the loop is on its own basetempo, no problem at all.

Is this a known issue or am i doing something wrong?
