The bits of pva all over the place is 100% normal. Unfortunately. and the tail.
However you should be using the default settings which include "horizontal expansion" set to 3mm. And I don't think you are using that. I find it a bit dangerous to have pva start and stop like it does in your print but if you increase horiztontal expansion then pva will have a path through itself down to the glass.
If you don't have a path down to the glass then you have pva sitting on top of pla which works but not as well.
Anyway this particular part does not benefit from pva as much as some parts do that have much larger, more serious overhangs. Like say a boat propeller would have. A boat propeller benefits greatly from pva. A totem pole benefits also but not as much.
But, yeah, pva is kind of a pain. It doesn't behave as well as PLA. PLA sticks to itself when still liquid. Like mucus or snot. PVA not so much - more like cement. Or peanut butter. When it's wet it can hardly hold it's own weight. One of the results is bits of pva chunks everywhere.

In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
