That isn't actually displaying the first slide, it's just a thumbnail showing what the default background is for that item. The main thumbnail of the song, scripture, and presentation in the schedule will always just show the background. When you expand the item in the schedule, then you will see the actual slides in it.
The slide in the first block on the schedule is blank with the name of the song next to the slide. How do I get the words to appear on the slide in the schedule? The words are visible in the center and live view screens.
