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.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
