With all settings enabled/checked, the guide progresses normally.  I have unchecked the checkboxes through ‘Show Ant Trail’ and no error encountered.  I will work through this more today as I have time.

    There are a lot of settings combinations to try considering it may be one or a combination of multiple. I am at a loss as to why I could previously reproduce the error, multiple times, on multiple computers by unchecking/rechecking the ‘Icon Arrow’ box.
