AB Quantum App Issue

Has anyone experienced an issue where from the Shoot, Ballistics Calibration screen, you define/add a DSF, select "Use DSF", but it does not change the solution (elevation) to reflect the change? For instance, with my .22 at 200 yards, Elevation is 6.21. I enter the actual drop in DSF of 5.5, then hit Use DSF and the solution does not reflect 5.5. I checked the DSF table, and the entry is there. Sometimes, if I select Environment, then get temp for example it will then update correctly. Other times it won't. Seems random.

Thanks
