Why is it doing this?
It looks like the face normal is reversed. I don't know why that would happen; it looks like a pretty benign shape. What happens if you run the stringent Check on the part? Another method to find problems is to export it to Parasolid, STEP, and/or IGES and then re-import it. Does the face come in OK?
if you hover over the face does it show an outline like it is there? if so sometimes the fillet cause a glitch add a fillet to the sharp edge and see if it comes back to test.....
Any chance if you upload the file to check??
I found that the surfaces curves were to tight to offset thicken.I checked to find they rippled when i did offset surfaces.
I ended up creating a new outer suface and knitted it to form a solid and by using combine solids I created the final solid.
