Top layer over holes?

[barkster]

should my holes look like this? I intend to thread them but the do not look like will be very strong. I would have thought the a top layer would go over the top of them but I guess this is as intended. To me it looks like those torus' will just twist right out. Do I have a setting wrong or is this as intended? I'm using a Ender 3 Pro. I did increase the Outline/Perimeter Shell value to try and help increase strength.

why isn't my attachment showing?

You are under extruding, increase your "extrusion multiplier". If you want the top to overlap the perimeters more, increase "outline overlap"
