I want to remove a manual lens from metadata panel

[Joe Foe Toe]

I have a manual lens appearing in metadata variations with zero images associated. (It was originally added thru Lenstagger plugin if that matters). I want it gone. How can I do that?

It should automatically disappear after a restart of Lightroom.

First thing I tried. After reading your reply, I restarted again and wouldn't you know, it disappeared! Only thing I can think is the possibility I still had the panel open with the cursor on this no-longer existent lens! Thanks.
