Something is blocking my gameplay view

Hi,

I am having difficuties whenever I click the play button. Please see the attached picture. In my MainMenuLevel I have hardly anything and when I click play a “BSP/geometry” appears and blocks the view. Any idea what is causing this? If I cancel the gameplay and move around on level and click play again the BSP/geometry wont appear again, but in case I click cancel and play right away without moving around the view is always blocked.

Thanks

.
