I have no idea, it doesn’t do that for me on my tests - how do you replicate your issue from a clear kit clear pattern using the fewest steps possible ?

The Lock Trigs can appear to have a different value (i.e. it’s the track default, relative to other normal trigs in pattern) and as long as they are not highlighted as locked (which you’d have done somehow) then I don’t quite know what you are seeing/expecting

You need to demonstrate using a very simple easily repeatable test

Also be sure to test this whilst connected to NOTHING else, not usb, nor MIDI … keep it simple
