Seam issues?

This print turned out near perfect, except for a section where the seam looks horrible. I double checked the seam on my slicer (Bambu Studio) and it was supposed to be on the side of the print, not slightly forward. What causes this and how can I fix it?

Printer model: Bambu P1s

Slicer: Bambu Studio

Filament: Bambu Matte PLA

Nozzle: 0.4mm, 220°

Bed: Bambu Textured PEI, 55°

Print Speed: outer wall 200 mm/s, inner wall 350 mm/s

Retraction settings: 0.8mm, 0.4mm z hop when retract, retraction/deretraction speed 30mm/s

Notes: I did a temp tower and it looked best around 220, but I may need to lower the nozzle temp. My printer also looks worse the slower the print speed is, so I'm hesitant to go below 150 mm/s for the outer wall. Thanks!!

Layer Misalignment/Underextrusion?

I'm printing some sailor moon wands for my friends, and I keep getting this weird layer misalignment in similar places on each print. It looks the same on both sides, so I'm unsure if it's a misalignment, underextrusion, or something else. What could be causing this and how can I fix it?

Please note I have multiple prints in this post, the temperature, layer height, and speed settings are for the MIDDLE print. The right print was a test with different settings, but you can see the layer issue on that one, so I included images as well.

Other notes:

I've tried printing the outer wall at slower speeds, but that just made all layer lines more visible.

I have also adjusted the layer height from 0.12 to 0.08. (The left print was 0.12, the middle is 0.08). All prints were printed with the top of the star towards the top of the printer.

This happens whether I print the model in two separate parts (the middle and left prints) or one full part (shown on the right).

Any suggestions would be appreciated for the specific issue or general suggestions on how to improve the quality of this print. I'm new to 3d printing, so thanks for the help and please let me know if I missed any important settings.
