The Lighting Controller

Hi I'm having a problem in the live screen. when i press a button to play a scene the selected scene will only play for a maximum of 20 loops before jumping on to the next button ect ect. However i need the scenes to remain on a continues loop once i press the button for that scene. Is there a way to fix this?

Thanks in advance,
Jordan.

By default ("loop" not checked), the scene continuously loops.
