Retraction is a complicated issue. there are several settings related to retraction. The one you care about is to try to prevent the filament from grinding. I have done prints with 500 Meters of retraction. In one print! That's a half kilometer! I have found that if the same piece of filament goes back and forth 10X through the feeder it is always fine but around 20X or 40X through the feeder and your print can fail.
Because of this there is a parameter that keeps you from retracting too much. I forget what it is called but something like "minimum extrusion before retraction" or "maximum retracts on same filament". Something like that. They have changed the name and I lost track.
There is *also* a parameter that prevents retraction if the gap that you have to pass over is smaller than a given distance. This is unrelated to your issue above but good to know about.

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
