Editing a chord symbol on any other page than the first page is broken
Open the attached score. Try to edit a chord symbol on page 2, 3 etc. While it's being edited, the text will appear on the first page, leaving the space where the chord symbol was blank. Clicking off the chord symbol to finish the edit returns it to its original position, with the text edited as expected.
Workaround is to just remember what you're typing :)
