Extrude function not able to select all contours even though they are the same?

I'm trying to create a series of flats on all the holes in the pattern. They are all the exact same, but only one is able to be selected in the extrude feature. When I checked the sketch for open contours it said I had one closed contour and no open contours. Please see attached images.

Thanks in advance!
