So I have this working...sort of.
As an administrator I can go to my UCP and set my custom title. I've created a test account and set it as a regular admin and it is able to set rank in the UCP. However, as a registered user the test account can't.
I went over my permissions again.

It seems the permissions are right to me. I purge/refresh the caches and the Custom Settings are: Replace Rank Only, 0,0,45.
Well, I found the solution, for me at least. I don't know if the other people with the same error have the Arcade mod installed but that is the problem for me. Since I admins are able to set their rank I went into the registered users group and into the admin permissions and turn everything on. Then I would go back and put NO for an entire section till I found the section responsible. Then I went and tried each one..one by one.
I went to ACP
--> Users & Groups
--> Groups' Permissions
--> Registered Members
--> Select Type [Admin permissions]
--> Advanced Settings
--> phpBB Arcade Tab
--> Can alter arcade permission class - YES
Enabling this for me let people see it in the UCP. I was afraid of what they could do in the admin panel since users can see the link to log into it. I logged in with my test account and all it shows you two tabs. 'General' and 'Arcade'. Under General they can only see the basic board statistics and under Arcade they can only see the User Guide. So nothing can be changed.
I can give my files to the anyone who requests if a solution cannot be found out. For now I am just going to edit the overall_footer file and get rid of the link to the admin panel so users don't make a stink about the ability to do nothing in there on the forums.
