You are very welcome!
I have noted this as an issue, in tomorrow’s plugin update there will be a core fix for it, so even if show_in_rest is not defined or set to false, the plugin will display the post type in the list correctly.
If you don’t mind, I will close this topic soon and mark it as resolved, feel free to open another one if you have other questions or issues.
If you like the plugin and have not rated already, feel free to leave a rating on the wordpress plugin repository, it’s greatly appreciated and helps us a lot!
All the best to you,
Ernest
