What happened to seam and walls near it?

Hello everyone,

this is my first post and I will be grateful for your help resolving this issue

I have not had such issue until now. Sunlu PLA+ white new from the box. Used tuned filament settings from Sunlu PLA+ Black

scarf join seam + aligned seam in settings.

wall thickness is 1.6mm layer 0.2 nozzle 0.4 temp 210 C

Why I have such bubbles near the seam? on the other side print is clear

There is also one issue in the bottom part which is a bit shrinked when going torwards the walls (3rd photo)

Thanks in advance for help
