P1S issue with print on spiral vase (single filament drop)

Hi Everyone!

I’ve been multiple iterations of my design to resolve couple issues and I did it with great success, but there is still one thing happening I cannot resolve.
It doesn’t happen on every print of this model but it happens every 2-3 prints on different heights.
It looks like single drop of filament, photo below:

When it comes to technicalities:
Using P1S with 0.8mm nozzle
Filament - Sunlu White PLA+ (dried before the print)

and slicer settings:






And retraction lenght changed to 0.4

I have different models I print in spiral vase with simmilar settings and it’s the same issue “single drop” on every other print.

Im losing my mind here…
