Have Per User and Per Device, how to manage my remote access?

 Hi.

 I had a windows 2008 R2 x64 and setup my RD, I start with 5 license Per-Device, but I got more users, my seller sold to me another 5 licenses but Per-User.

 I add my Per-User licenses done, status:

Per-Device 5 available 0 ok

Per-User 5 available generate report issue "-"

Now, in total I had 8 user, 5 of are using Per-device, now how can I force the others to take the Per-User licenses?

Before I add more license, the users could access the server, but some of them where using the temporal license, do I need to delete something in the server and user side?

Any input will be appreciated, thanks!!!
