Ok, I have some problems here, and I don't know if it's reproducible, if anybody from the staff can check, or anyone from the forum can confirm, would be greatly appreciated.
here's the video. The issue is reproduced twice on different tracks.

EDIT.
I FOUND that what causes this bug is holding one or more keys on while setting the chord, like it was needed for the previous firmwares. so the bug still exists, but if I go in CHORD MODE once or twice and press the keys separately, it gets unstuck after a couple of times, but changing abruptly on the shift settings (blue leds).
THIS is just provide to troubleshoot and to provide a workaround, the bug still persists in my machine/firmware.
