Rekordbox DJ Slicer issue

Hi ,

I am a retailer for providing Pioneer products.

I have tested the DDJ-RX, DDJ-RB with rekordbox dj, (even I use rekordbox dj without midi controller has following problem)

but , I found a problem. for example: I open the software and drop the track to deck A. if the track is dropped first time, then, the rekordbox would analyzed the track. wait for 10 seconds, the grid would be set!!!  But I press slicer button on the deck A is not working. the wrong message is " input BPM in the grid panel.   I check the song grid on the software, but the gird was be set and BPM also display on the deck.  and I drop same song to deck B, the B slicer is working fine!!!!  or, once I reopen the rekordbox, and put the same song to the  deck A, the slicer is OK again.

so, it should not grid problem.

so, this is should be a bug.
