Horrible bridge in 10mm hole top.

Hi all. I have a small credit card sized magnetic rack ID support that I am printing. The print fits a 10x2mm magnet. I am trying to keep the part as thin and light as possible because I need to print several hundreds of them and want to save as much material as I can. In the images, you can see the print has a small 10mm hole for the magnet. The issue I am having is the bridge. It is crap and sagging and therefore, the magnet doesn't sit flush to the part as would be expected and stick out as much as 0.6mm from the surface. Seems to me that Orca is adding a wall in midair, and then trying to bridge that. I have attached 2 screenshots. I can't seem to find the right setting in Orca to avoid this behavior. Any help is greatly appreciated.
