Displacement code checks. Bar displacements versus maximum deflections

Two related issues: While running a code check, I noticed that the "uzt" deflection calculated under the "RESULTS" - "Displacements" - "Bar Deflection" was much less than the displacement calculated through the "Diagrams" - "Deformation" - "Exact Deformation for Bars" method.  In both cases, I have chosen the same load combination (10: DL+SL).  As I looked into this issue, I noticed that under "Bar Properties" the "Current value" is -3.44" with "Bar displacements" set and 1.51 with "Maximum deflections" selected.  This latter value is the one I see through the code check process (see attached PDF).  Interestingly, this is not the backspan deflection (not sure what it does correspond to).  Can I specify that the code check look at "Bar displacements" rather than "Maximum deflections"?  

 

Thanks for any help on this issue!
