I have found that the setting “Heading at First Screen” and the act of hiding text or black screen conflicts together.
I have found that when the text is hidden or the screen is black, accessing the next song or a new bible verse ready for display, then un-hiding the text ends up not displaying the heading correctly when the “Heading at first screen only” setting is enabled
Whereas sending the new song/bible verse across without hiding/un-hiding the text does display the heading at first screen correctly
(Hopefully that makes sense)
