I have several custom posts that I have made with custompress. I also have membership 2 pro installed that I use to manage users access on my website. However the membership access field with Enable Protection in it shows up on the standard post editor but not on the custom post editor.
I've attached two screenshots, one with the field I want to add (highlighted with red box) and a screenshot of the custompost without it.
Any help in resolving this would be greatly appreciated.
