drawing diameter dim not working

Hello;

      Anyone ever had the diameter from  the centerline in a profile view stop working. This is when you drag the dim down. I have a detail, & it worked fine, but now trying to put a couple more dims on it, it will just give the center to one half dim. Also I can't get it to work on the ones I already did a second time.  It is a section view.

Thanks, for any input in advance.
