Pay Per View - Edit User Access Manually?

I see that as an Admin within the Users section there are two boxes where it appears I should be able to edit the access that user has to PPV content:
"Expires At" and "Recurring Days"
[image pos="0"]
I've tried manually entering time and recurring days in these boxes but it seems to have no affect when I login as that test user.
I don't see any documentation for these settings in the Plugin details.
Can you please explain their use?
