Game Mode returns "None" when placed inside of a folder with parentheses in the name

Game Mode returns "None" when placed inside of a folder with parentheses in the name. After adding parentheses to the folder name containing the Game Mode, the game mode is then set to none if selected in the project settings.

1. Open the first person template
2. Change the name of the blueprints folder to "Blueprints(test)"
3. Open the project settings
4. In "Maps and Modes" Change the Game Mode to anything other than "FirstPersonGameMode"
5. Try and change the game mode back to "FirstPersonGameMode"
6. Notice that the game mode is set to "None"

Expected: The Game mode would be set to "FirstPersonGameMode" instead of none regardless of the folder name
Result: After adding parentheses to the folder name containing the Game Mode, the game mode is then set to none if selected in the project settings
