My Main Menu map level is black (widget working fine) when packaging my game, but works in stand-alone and editor mode. Yes, I have add it to the "List of Maps to Include" in the Project Settings.

As mentioned in the title, my main menu map is black when packaging my game, but works in stand-alone and editor mode. And before you ask the obvious first troubleshooting question, yes, I have add it to the “List of Maps to Include” in the Packaging Settings.
The weird part is that it works fine after I return to the Main Menu from the Pause menu inside the game. Screenshot 1 is what it looks like on launch, and screenshot 2 is what it is supposed to look like, and looks like after I play the game and return to the menu afterwards on the same instance.
Settings image included. Any ideas? Thanks!
