Let's say a drop-down has the following values:

A,B,C,D

The admin logged in and added new values E,F and marked Active to "True". There is no issue here.

The admin modified the value for A,D to X,Y making Active to "False" for A,D and marking Active to "True" for X,Y.

When I query values from the table where Active is True, it would fetch me B,C,X,Y,E,F (B,C no changes. A,D has been modified to X,Y & E,F has been added.)

What if old instance had values of A or D selected? The process variable will have the value "A" or "D".
