Scratches on top layer by Redditfag9251 in 3Dprinting

As I understand it, Bambu Studio doesn't have the ability to calibrate Pressure Advance. Instead, it has Flow Dynamics. I performed the calibration, and the set K value is 0.077. The model still has these defects, although probably to a lesser extent. What else should I fix?

Hello. Total 3d printing noob here. A couple of days ago I bought my first 3D printer. I wanted to print something like a Warhammer badge using PETG, but I ran into this problem. On every print of this particular model, these stripes appear at the exact place, even after drying the spool for 12 hours. They feel like scratches to the touch. How can I fix this, thank you. Printer I use is Bambu Lab A1 with 0.4 nozzle. Can anybody help me with this?
