Currently, data saved in boolean values and drop-down boxes from the personal server pages is kept and defined even as the game mode is switched from "personal server" to "game place"; it is still applied to the servers of the actual game.
For example, if I were to associate my personal build server with a group and then switch the game type back to "game place", the game would still appear under the Personal Servers tab in the group itself.
I created an example for any developers.

As you can see, the first place in the queue of "personal servers" is actually a regular game, whereas the second is a legitimate personal build server.
