DDJ-FLX10 + Rekordbox: Slip Roll unable to move to different channel.

Hi,

This is a problem only appearing on the faders set to Rekordbox. 

While the fader channels are on Line, I can make a Slip Roll loop in the effect section and then move them to a different channel by changing the FX channel. 

When the fader channels are set to the A, thus Rekordbox, I can make a Slip Roll loop, but when I move the FX channel, the sampled audio does not move to that other channel. 

Rekordbox 6.8.5 on Windows 11 

Many thanks!

Ian
