Can't DELETE or RENAME *unused* parameter

[autodeskHCGNN]

I have a legacy parameter that is no longer reference -- I can confirm this by searching in the Parameter list.

When I try to delete the parameter, I get the error message:

Parameter 'XYZ' can't be deleted. It is used in the expression of another parameter, ""

 Note that other parameter has no name!

Even more strange, it seemingly allows me to RENAME the parameter in the Parameter list, but the renaming fails to stick. I.e., when I reopen the parameter list, the parameter name reverts to the original name.

Bottom line is that I can neither rename nor delete this unused parameter!!!!

Any suggestions?

Double check for where the parameter is / was used.

Might help….

I certainly double/triple/quadruple checked before posting... I even exported all the parameters to see if the parameter is referenced anywhere else. It's not.
This seems to be a bug...
