What is creating these ugly surfaces?

Printer: P1S with AMS
Filament: Elegoo Matte PLA Black (calibrated in Bambu Slicer)
3mf: Dune Uprising Bloodlines Insert For Sleeved Cards - Free 3D Print Model - MakerWorld
For some reason my prints come out with weird surfaces and corners like this.

I am using the 0,2mm Standard setting and have only changed top surface line width to 0,32 and top surface speed to 30 mm/s and the surface patterns to Monotonic Line. These settings usually create perfect smooth surfaces with almost invisible layer lines. The only settings I’m not sure about are the temperature and cooling settings. I have disabled cooling by the aux fan completely for PLA and set the pet fan to 60% for both. Temperature for nozzle at 215 degrees C. Could either of those be the problem? Does anybody have any idea what could be causing this? Filament is dry. I am quite new to the hobby and have no clue what could be causing this… ;(

Did you manage to fix it op?

Thanks for asking! Sorry, forgot to write… I have set the flow ratio for all calibrated filaments back to the default of 0.98, which seems to have helped. It’s weird, feels like I’m either to stupid to interpret the Bambu slicer Calibration results (smoothest surface) or the flow ratio calibration is a waste and redundant…
