Issue with opening game level from main menue after packaging game

So I just did a test build of my game and for some reason my Main menu is bugged but only on the packaged project. My main menu is in a separate level and I am opening my game level when the play button is clicked as seen below.

But for some reason it just keeps bringing me back to the main menu instead.

Can anyone tell me how to fix this?

I fixed it. And all thank to Matt Aspland. He is a god on YouTube for UE development. Anyways what I needed to do was go into the project settings → Packaging → Advanced and tick on Cook only maps (This only affects cookall) and add all my maps for my game into the List of maps to include in a packaged build. see attached video for how to do it.
