Display Character Error

Hey I've been recently running into this problem. It appears also when selecting a folder with projects inside them. But in the case its a square with a "?" inside.

On your Mac, go to the OmniFocus preferences. At the bottom of the first or second screen, there's an option for setting the character used to separate components in a hierarchical name. If you reset that to something printable, the issue should go away after the next sync is complete.
