Problem recording using Rekordbox

Hello,

I recently upgraded Rekordbox to 5.8.0

I'm using Mac Mojave 10.14.6

I have a DJM-250MK2, which is connected to the Mac using USB.

When trying to record a set (Rekordbox is on Export mode), the recording stops after some time. It happened several times. Sometimes after around seconds, 90 seconds or other. But it stops although I continued playing.

Before upgrading Rekordbox I never had this problem. The recording continued until I pressed stop.

Any suggestion?

Thanks,
