External Plugins adding new, same name.

Hello

Got a new computer, but use the same template.
the external plugins got a missing plugin warning, thats okay, I can just delete them and add new.
but here is the question, cubase seems to know that “external plugin name” is there, so when making a new it rename it to “external plugin name 2”

How can I delete the missing external plugin from the system, so I can use the same name as before

Thanks
