RCP plugin integration

Previously when duplicating a page, I could change the restrictions with the Restrict Content Pro plugin. E.g. Changing the memberships or assigning a new membership that could view the page when editing a page.

However, whenever I try to change the settings on restricting the page and save the changes (press on update in the edit page); afterwards refresh the page, the settings set by RCP are not saved. This happened recently, so an update might’ve made the plugin incompatible.

No caching plugin is enabled or anything else that might conflict with this. I’ve tried to create a new page without the duplicate option, and afterwards was able to change the settings in the edit area from the page. Hence, I suspects the issue is the duplicate page plugin… Any help would be appreciated.
