I’m having a similar annoying bug wrt the AMS. I have 4 rolls of ABS, red, blue, grey, white. I slice a part using red ‘A1’ when I click print the filament show red, but below it is A3 which is grey. Out of pure frustration I yanked the grey out, then it selects A4 ‘white’. I’ve been using the latest FW and BBS for about a week and this only appeared yesterday.
