Kong appending "/default" to the paths of my cookies. How to override?

I updated from Kong 3.0 to 3.4 (using OIDC). It seems that kong is now appending “/default” to the cookie paths it sets (such as the authorization and session cookies). Even if I set the authorization_cookie_path and session_cookie_path configuration values, it still takes whatever value I set and appends /default. This is causing me issues because I want my session cookie path to just be /. Please can anyone tell me if there is any way to change this behavior? This is causing me issues with logging out of the developer portal as the session cookie seems to get dropped along the way.
