Assuming the apps themselves have nothing to do with it (shouldn't but still).

You are wanting to look at a couple of settings. You can set these via GPO as well, but assuming a single RemoteApp server, the GUI is easy enough.

In the Remote Desktop Session Host Configuration right click on RDP-Tcp and choose Properties.

In there click on the Sessions tab and verify the settings are what you want them to be:

Then close that screen but leave Remote Desktop Session Host Configuration open and verify that Restrict each user to a single session is set to Yes
