Possible conversion/translation issue

I have a drawing done in AutoCAD  web that I am saving to a local file and opening in Illustrator. The drawing, a DWG file, mostly looks fine in Illustrator, but a few of my hatches do not. One of them, is a square with a hole in it. When viewing it in CAD, the hatch fills out the square minus the circle in the middle, When I open the file in Illustrator, the square is 100% filled in. The other example is, I have a large circle with 2 smaller circles inside so it looks like a ring around a small circle. I did a hatch to create the outer ring and the same hatch in the small circle in the middle. Neither hatch shows up when I open in Illustrator. I have dozens of other hatches in the drawing that come out fine. Any idea how I can fix this?

I tried to attach the DWG file that I;m working with, it it isn't supported in this forum site
