Projected curve not projecting completely

I've been projecting sketches onto some of the more complex curved faces on my model and there is one sketch in particular that is straddling two faces (one an original feature, the other a mirror of it). It will project onto the original face, but won't project onto the mirrored part. Whenever I setup the project it will show it in preview as if it will work (even if I make two seperate projected curves for each side), but whenever I hit ok it tells me to "please select a sketch and a face(s)", even when it is CLEARLY selected.
