Cannot select face, Curve driven pattern

Creating a curve driven pattern. I have the helix/spiral set up, the feature to pattern (an extrude cut) and when I go to select the "Face normal" SolidWorks sometimes seems to completely disregard my selections. I've had this issue before. Sometimes it works, sometimes it doesn't. What gives? I'm trying to select the face a of a revolve-thin, and as I've stated I've been able to select it in the past and get my result. Is this a bug?
