mainstage Vintage B3 recording with Sustain Pedal

Hi all, i have a problem. When try to record a patch with Vintage B3 when i play and use Sustain Pedal (64) for vibrato, Mainstage 3.2 export multiple record files , i try different .aiff or .wav . This thing not happened when i don't use Sustain Pedal ore i use some other internal or external Mainstage audio units.

Thanks best regards
