A1 AMS Lite leaving streaks of darker filament in lighter colours

Bambu Lab AMS
1

Printing something like a coaster and it has 3 colours on it, one is black and I find it is leaving little streaks of black in the coloured areas, almost as if there is some filament oozing when its moving about into the coloured area

You will only see this when you have 2 or more filaments loaded into the AMS in Bambu Studio.
You can get away with setting it to 0.50 most times…except for transparent filaments.
Also, use a purge tower.
