This will be fixed in the next release of ptxprint. In Header+Footer, if you have Include References: Verse turned off, then the RangeIndicator is used from your Paratext settings. This can and often has a | in the middle for some yet to be determined reason (can someone explain?). We will trim all that in the next release. For now, if it still offends you, turn on the Include References: Verse and it will look nicer, even if it isn't quite what you want :)
