Word Highlighting cannot change Highlighting Start

In come cases when I record word highlighting I cannot edit the starting point.  In the Start Highlighting dialog the starting point is after the ending point and a new starting point cannot be saved.  (see screen capture)

Not sure how to recreate it, but it either happens because I start tapping before the countdown has finished or after the last word has been spoken.  When this condition exists the words start wapping around to the beginning of the paragraph.

The work around is to delete the word highlighting and to recreate it from scratch.
