Problem creating a menu file for the title page without seeing the yellow line

In photopia I can't create a custom title page like I could in proshow.   I tried several options but when I play the blue ray the title page has a yellow line around something visible and detracts from the appearance of the title page.  In proshow I created a custom menu and added a layer that was just black color and enlarged it a bit larger than the screen and selected that layer to be the one that started the slideshow on a click - then the yellow box around it was not visible on the title page.  Does anyone have a tip for creating a title page in photopia without the visible yellow line?
