UNABLE TO EDIT/CREATE MEMBERSHIP ATTRIBUTES

I looked in the console and found several errors where the plugin was requesting assets that are not there, and unless I am mistaken there is a typo in the request.

For example it requests:

https://xxxxxxxxxxx.com/wp-content/plugins/membership//app/addon/attributes/assets/css/attributes.css?ver=4.6

First off on the server, beyond assets there are no other directories, just a php file, second I may be mistaken, but between the membership and app directories there should be only one slash. All of the requests with errors have that same double slash and there are 2 css files and 2 js files requested that don't exist.
