Heyy so I'm trying to make a sketch on sheet metal, but my solidwork program keeps saying "open contour", when I try to go to tools > sketch tools > check sketch for feature > sheet metal base flange, it shows me that there is a 0.18 mm gap but no magnifying glass appears. How can I activate the magnifying glass so it actually shows me where the problem is so I can fix it?? This might sound silly which is why there is no answers for it so far in the forum... 

I have attached images of the problem messages + the contour gap they are "showing" me...
