Removing adressbook

Hi, I accidentally added an address book, when importing my calendar from Google. Now I have all these duplicates in my contacts. When I try to remove it, it says it failed.
Any ideas?

Kind regards,

Bas

as a temp workaround you can hide an address book in the Contact App settings

I haven’t a google account setup, so not sure - but I guess you can go to Settings->Account and dissociate the google address book and keep the calendar? a user that has this setup could maybe confirm.
