I have don't know why it's just in one spot. If you like puzzles you could look at the layer view and run through the order of where it starts printing first on a layer or after a long "travel" move and there's a good chance the bad areas are underextrusion just after a long travel move or are the start of the layer (in which case a prime tower would help - check the "prime tower" box).
But pretty much any PVA issue is improved by drying the PVA. So consider doing that:
1) In cura, after slicing, look in the lower right and note how many meters of PVA will be used.
2) Unspool that many meters of PVA and put the pva directly on the heated bed with the spool on top (no need to cut the filament).
3) Set the bed temp to 60C. Cover with a towel. Let sit for a few hours. 3 hours is usually plenty. I'm not sure how long it needs.
4) Print with the dried PVA immediately. As soon as the print is done put the pva in a ziplock bag. no amount of desiccant seems to be enough to keep it dry so do this procedure before every print.

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.
