How to reactivate a downgrade right

[Dale W]

I'm setting  downgrade right and getting the error message:  An inactive downgrade model already exists, please re-activate it.

I'm unable to find a location where the inactive downgrade rights are listed, in order to reactivate it and wasn't able to find information in the docs/help. 

Can someone please let me know where I can go to show those Inactive Downgrade Rights, please?

I found the solution, from a co-worker.

Go to the Software Models, scroll down and pick the Downgrade Rights.

Remove the filter:  Active = True

Pick the inactive SW Model, Click on the 'False' and set it to Active.
