How to avoid the jumps in the deflection diagram during the Construction stages?

Answer:
The jump in deflections in same girder can be avoided by viewing the results by checking on "stage/step real displacements" option as described below with help of an example.
we have modeled the 2-span girder activated in 2 construction stages as shown below.

Construction stage analysis was performed where only dead load due to self-weight was applied.

After analyzing the model, displacement contour due self-weight for construction stage 2 is observed. The jump in result is observed.


But now, when the results for displacement contour are viewed by checking on the Stage/Step real Disp. option, the jump disappears as shown below
