I started with a content slide that had the normal text field plus one custom text field. I added two custom text fields when I suddenly realized the content slide had split in two, like a song slide. The two slides were identical except the normal text field was missing from slide 2. I could not delete either slide without deleting the other (just like a song). I backed out each change that I had made so that I now have the original slide 1 and slide 2 has the custom text field, but not the normal text field. If you want to look at my presentation, it is the Apr 30, 2017 and the slide is the birthday slide near the bottom of the pre-service loop.
Of course I can start over, but thought you might want to take a look.
Thanks,
Brendon
