Well, a few things;
First, when you upload a drawing you need to save it as a Package file then upload that package. When I open the drawing I get a warning that the part is missing.
Second, I was able get the hatch to fill in by deleting your hatch and recreating it. I carefully selected the border geometry but there is still a small spot where it doesn't recognize the border. You can see it at the bottom RH corner.
And finally, I was not able to Activate Sketch in View for some reason. Maybe it's related to the missing model.
You may want to send this to Support for review unless someone on the forum can figure out what's wrong with it.
