Remove older instances of Kontakt from Native Access

Hi,

Does anyone know how to remove older instances of Kontakt (in my case, 6 and 7) from Native Access? I'm doing the auto migration option and have manually deleted all the relevant files from these apps. Yet they still appear in Native Access with the orange exclamation point alert and a prompt to "repair." This is visual clutter and I want to remove it. For some reason NI doesn't give you the option to uninstall.

I've asked NI support multiple times in email threads and they just won't answer this question.
