Issue with custom Selector, ID or classes not saving

Hi there. I love this plugin but have come across an issue that I cannot seem to solve. I have 4 custom user roles that I have created and every time I get to “Write options – Page” and try to check off a (Selector, ID or class) setting it never saves and is actually really buggy. Sometimes it saves only one user role column and sometimes it doesn’t. I’ve tried disabling and reenabling all plugins on the site and am still getting the same issue.

I really need help on this one. I’m hoping someone could help.
