Opening Gameplay Debugger while in PIE removes print string output from screen in subsequent PIE modes

If a user opens gameplay debugger ( ' pressed while in PIE), all print string outputs to screen disappear, and will no longer appear during any PIE session until editor is closed and re-opened.

Workaround: Pressing ' a second time will remove Gameplay Debug mode, allowing tick to be seen again. If a user enters PIE, they can press ' twice to go back into Gameplay Debug mode, then turn it off again to see the print string.
