Hello, today I got my "New Flirc", I bought it directly from Flirc. OK, my device was pretty dirty and seems to be a used one, but it's not the problem. If I try to set up the buttons on my remotes, it does only work for 2-4 buttons, and then I get the message "Button already exists". What I've tried: Erased all buttons;Cleared the configuration;Forced firmware update.Remotes I've tried: Samsung TVOnkyo AV-ReceiverLogitechSqueezeboxXiaomi TV-BoxApple Remote (white)Computers I use: Mac MiniiMacMacBook Air.Thank you in advance.
