Unable to complete fields in OAuth 2 clients area in the Settings > Security area


Is there anybody else who has had this issue where the fields are not clickable in Nextcloud 14 for the OAuth 2 Clients as seen here in Nextcloud screenshot:

I was going through this page here to try setup up SSO between Nextcloud and Wordpress. https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/oauth2.html

Any help would be great. It is like this on 2 instances I have of Nextcloud.
