Folder Iterator: Can't find Variable

See attached picture - the variable cannot be found, and generates the following error when run:

Error expanding Starting Folder : [Expression Error]: Variable\Object “PendingRoot” does not exist! [%PendingRoot‸%]

Notice the strange character just before the closing %.

Downgrading to resolves the error.

We really need to see the project file for this to figure out what is going on. Please send the project to support @ so we can try to reproduce the problem here.
