The problem is that the model has conflicting "normals". The top of the model (the "walls") has the normals facing outward, the bottom (the modeled "brim") has the normals facing inward. This confuses Cura. You can sort of see this because the top section has a red "overhang" indication on top, instead of on the bottom.
The easiest fix is to download the Mesh Tools plugin from the marketplace (if you don't have it already), select the model and right-click. Then select Mesh Tools -> Fix model normals. After that the model will slice properly.
If you look carefully at this image (that you posted yourself), you can also see that there is an issue with the normals. Looking at the small section between the tail and the head of the cat from below, you see that you are looking "through" the wall as if it did not exist, and then instead you see the insides of the wall. It looks asif you are staring into a box, as it were. This is due to what is called "backface culling"; the application that made this image did not draw the "back" of the faces. Since all the faces are "inverted", only the "insides" of the walls get drawn.
That did the trick.
I didn't really flinch at the strange representation in SW, since it sometimes loads models that actually slice correctly in a strange manner. But the Mesh Tools extention with 'Fix Normals' did indeed fix the stl model for slicing.
So you're definitely right.
Thanks a lot for your help. ❤️

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.
