Ok, I uploaded a new version to the App Store. You should get the update as soon as it is approved. In the meantime, you can work around the problem by taking a screenshot of the fingering by typing Command-Shift-3.
Thanks for the report! I don't know how I didn't notice that before. I will work on a fix ASAP and push an update to the App Store. It might take up to a week for Apple to approve the update.
Sorry for the trouble!
Haha, you're guess is as good as mine! I'm sure there's a lot of history involved there. And keep in mind most of this was not originally done in English, so it may have made better sense in the original language.
