PLA-CF catching in the tubes/ frequent filament purge

Bambu Lab AMS AMS lite
1

I am currently using PLA-CF with my A1, 0.4 hardened noozle and AMS-Lite and tho the print is fine, I see the filament having lots of friction in the PTFE tube/ gears in the AMS-Lite. I also have the issue that when printing, the A1 needs to purge new filament frequently.

I guess it’s due to the system having difficulty feeding the filament but I have no idea how to solve.

CF is one of the filaments that Bambu says not to use in the AMS…only Bambu PLA-CF.
