Can't save after deleting duplicated input parameter from DUT

Create a DUT Type and define a variables group with at least one variable. Then create a DUT based on this DUT Type, add a test input parameter, and save. Next, edit the DUT Type to add a test input parameter using the same variable, and save. Finally, edit the DUT to remove the duplicated test input parameter and save.

 

Workaround:

Remove test input parameter from DUT Type. Then remove it from DUT and re-add it to the DUT Type.
