Cura keeps adding support material where there is no overhang.

I am trying to print a cylinder with a few small square notches in the exterior wall that do not penetrate the interior wall, yet Cura keeps adding way more PVA support material than is necessary. On top of that, Cura insists on printing support inside the cylinder that is not connected, nor supporting, anything.

Can someone point me to the setting to change this so that Cura only puts fill material inside the holes?

It's the "horizontal expansion" setting. It's on by default because PVA does not stick to well on top of PLA, so it helps building PVA up from the bed.

That was most definitely the problem. Thank you very much!
