[Koha] OPACSuggestionAutoFill - must be set to 1 or 0

Hello all, Koha 22.05 I've been adjusting settings for purchase suggestions and tested out the Google Books API, after adjusting this setting in System preferences I now get a warning on the system information page: Warning : System preference 'OPACSuggestionAutoFill' must be '0' or '1', but is 'yes'. when set to enable or: Warning : System preference 'OPACSuggestionAutoFill' must be '0' or '1', but is 'no'. when set to disable. No message was there before adjusting this preference. Kind regards Christina
