[Koha] Local use preference OPACviewMARC doesn't switch off?

I somehow missed this part of your original message. Preference can
show up under Local use if they're not officially part of Koha. If you
had a customization at one time which included that preference it
would make sense that it is still around even if the customization is
long gone.

It's not part of Koha.
