Midi note mutes track randomly

Could someone check if this behauvoir happens on their OT. Or is this perhaps already a known issue…? I’m using an FCB1010 to send some midi to the OT. I have nothing connected to the Midi in on the FCB, so no midi echoing should be happening.

Midi CC 53 value toggled between 127 and 0 doesn’t do anything to regular rec triggers, but arms the rec track if it is an one shot trig. (Is it not possible the rec arm other than one shot trigs via midi?)

Midi note 35 is supposed to start/restart sequencer. It does, but also randomly mutes the active track if pressed multiple times in a row. (I have checked, it is only sending the note 35 and no hidden CCs) But it also sends a note off message when released, could that be the cause of this behaviour?

Are you sure that the CC and the note that you mention are really the ONLY things the FCB1010 sends out on the corresponding buttons? I know that the FCB1010 can be set up to sends loads of different CC/PC/Note messages simultaneously so maybe something else going out too.

Edit: Sorry, I just saw you checked for that.
