No matter what number is displayed on the jog for beat jump/loop, the amount that it jumps or in the track is 4. Oddly enough, the loop activates the correct number of bars. As the video shows, I am in an 8 count loop, but it only jumps ahead by 4, otherwise it would jump out of the loop.
This is after the most recent update, and I did try turning it off and on again.
Shift + Beat jump will change the value. You can adjust the beat jump length by pressing and holding Shift and pressing either Beat Jump button (PRIME 4, PRIME 2, SC LIVE 4, and SC LIVE 2), or by using the Default
Beat Jump Size setting in the User Profile menu.
To set the auto loop length, turn the Auto Loop knob to select the number of beats
