Infinity3

Hi. I am a new Infinity3 user. I have a beat buddy connected to infinity. From BB are sending midi clock. Settings Infinity3: sync = off + series (verse - chorus). Usecase: I press loop1, start recording and end the loop with the stop button. If I play loop1 and have CUE set - the sound changes the tuning. Why? If I have cue and fade turned off, then in the same procedure the tuning of loop1 does not change. Likewise, if I end loop1 by pressing loop2, the sound remains unchanged - ok. The problem is only the CUE setting and ending loop1 with the stop button.
