HAlion Sonic Selection note cutoff issue

I record an 8 bar midi file with the HAlion Sonic Selection instrument using the chord pads and play them back in loop mode.
Expected result:
All the notes are played as recorded.
Actual result:
When playing back the recorded file in loop mode, on the first cycles everything works properly, but after 2 or 3 cycles, the notes at the beginning of the bar are cut. I quantized them to be sure they are really positioned at the beginning of the bar but it didn’t solve the issue. The only way to solve the issue was to slightly delay them manually by deactivating the grid mode.
