2012 r2 Standard using RDP for Remote App screen lock issue

I have setup a brand new Windows 2012 R2 STD server running a domain. I have 4 RDS CALs installed in per user mode for the 4 users accessing this server. I have an app installed on the server that is sql based. The users launch RDP and in the advanced settings of the RDP connection, it is configured to launch the sql based program upon login to the server. Everything is running perfectly except that when a user gets up from their workstation to go to, say, lunch, the users minimize their RDP window. Upon returning, the remote window, when maximized is asking them to log in (essentially locking the remote computer like your local workstation would behave when left sitting too long.) With that said, here is what is configured:

1. Local workstations have their screen savers disabled and the setting to require login or welcome screen from screensaver is disabled as well. These machines stay running all day long and never require users to log in after any period of inactivity. (yes I know the security risks but this is what the client wants and cannot be changed so don't bother mentioning it)
2. On the RD Server, in Remote App Properties, I have the Session settings configured to never end sessions. See attachment.
3. In Group Policy, the Default Domain Policy is defined with these settings as well:

-Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits = Enable “Set time limit for disconnected sessions” and keep the “end a disconnected session” at Never

-Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections = Enabled “Automatic Reconnection” and “Configure Keep-alive connection interval”

-Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits = "Set time limit for disconnected sessions (set to enabled/NEVER" SEE ATTACHMENT

-Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections - SEE RDS CONNECTIONS POLICY ATTACHMENT

The client wants the remote app session to be just like the workstations to NEVER log off nor ever lose their session. They want it to be available 24/7 with no need to log in, even after they leave Friday evening and come back to work on Monday. What am I missing?

The server that hosts the application ALSO has to have these settings that the client computes have (screensaver / no password on unlock)

David, thank you for your suggestion. I have confirmed that the server has the screen saver disabled and set to not require sign on when resumed just like the workstations. Any other ideas?

do the same in power settings

Issue turned out to be the registry would not undo the group policy that was applied.
