Easy to reproduce. Only way to “edit” is to remove a verse ref and re-add it. Not sure if "write-once" is the intended behaviour, but sometimes I find I accidentally add an entire book (for example, I'll type Gen and then when the dropdown appears, I'll select Genesis and press Enter, but instead of adding Genesis to the textbox, Genesis 1 is added as verse-ref. Then there is no way to change the passage ref to something else (like Gen 1:1, etc)
