I think these strings are what I call a sort of "landing strings". I don't know if there is an official term for it. What I mean is that while traveling through air, the nozzle may leak a bit, and when encountering the next wall, that little drop is deposited on the side of that wall. On the next layer, the leaking drop is deposited on the previous drop. And then on that drop. And so on, causing weird upwards and outwards going strings, like insect antennas. It is a guess, but it is the only thing I can think of.
I do not have a good solution, but any solution (if this is indeed the problem!!!) should go in the direction of causing less leaks, or less movements through air, I think. Maybe print cooler and slower (=less pressure in nozzle), or travel faster through air, or travel over land instead of through air where possible, or more cooling fan, or changes in retraction settings (or maybe the printer doesn't even do any retractions when printing supports, which is why it leaks),...? Try watching carefully what happens while printing.
I do notice something similar when printing PET, which is more rubbery than PLA: so when printing overhangs or when traveling through air, it does not cause thin strings or hairs, but a blob under the nozzle that is deposited on the next wall or next obstruction that the nozzle meets in its travel.
Thanks for your reply. I think that is what is happening. I have messed with the retraction settings and printed with cooler temperatures but it is still doing it. I guess I could try slower print speeds but I'm not sure how that will help. I did try the "optimize wall printing order" feature but it did not help.

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.
A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
