LEAP Bridge Substructure Cap Design

I'm designing a hammerhead bent using moment magnification.  In the A/D parameters I have selected to design the cap for magnified moments.  Once the analysis is complete I design the column and check the design status.  I then go to the cap, select design status and I'm prompted "...please design all top columns using PDELTA or Moment Magnification! Please review!"   Yeah...that's what I just did.  Is this a bug?
