I have the same problem. When I load a part from Maker World with for example two colours and cklick then on synchronize then the colours match not to the colours shown in the device in Bambu Studio and the last one (nr. 8) is alway empty. I must add then one. When I cklick on each arrow on top of the filament in the device windows and synchronize again, then it works.

After sync…
