Hi 2Darc,
That is NOT a bug but normal operation! You use two layers and the fader needs to catch-up on the fader position it was before. Hence the green triangle showing you where to go with the fader.
Edit to clarify with an example:
On layer A you play a track at -6%. You switch to layer B and change the fader to, let’s say, +4% position because of the mix or whatever. If you then go back to layer A, the position of the fader would not be -6% anymore, so the SC will indicate to you (with the green triangle led) to move the fader to where it was. When it’s at that previous -6% position, the fader has caught-up and starts working again.
This catch-up is also active when you change the pitch range of a playing track.
You seem to have 1.2.x.? Could you perhaps show us the filename that’s on the flash drive you’re trying to update with?
Also remove the blue USB3 cable if connected to a computer while updating with a flash drive or else it’s waiting for input from the computer update procedure.
Don’t know for sure if the flash drive needs to be FAT32 for the purpose of updating that way. Mine is.
