Thanks. I got access to your site.
It seems that described issues with test user sjwtest were gone. Please confirm:
– I see “Log Out Everythere else” button at his user profile;
– I see “Posts/Pages/Custom Post Types Editor Restrictions” section configured to “Allow” to edit 4 pages and 4 posts categories.

As about access to the media folders for restricted user. When you apply edit restrictions to a user, such restrictions are applied to the Media Library also. Restricted user sees at the Media Library his own items (images) only. If there are know images uploaded by this user, he will see the empty Media Library.
If you wish to allow to see full Media Library withou restrictions you can use custom filter ure_attachments_show_full_list. Let me know if that helped.
