Resource Dependent Activities & Remaining Early Finish Date

I’m using resource dependent activities with dayshift and nightshift resources with calendars laid out accordingly.  Occasionally, I get the “Remaining Finish Date can’t be earlier than Actual Start Date” pop up. 

I’ve narrowed the conditions that cause this:

• The activities are 2 shift-10 hour-6 day calendars.  The dayshift is 10 hour (0700 – 1730) & nightshift is 10 hour (1800 – 0430).
• The activities in question have uneven shifts like 2 dayshifts and 1 nightshift.  The opposite hasn’t reproduced the issue, nor if the shifts are equal like 2 days and 2 nights.
• It only happens when the activity is in progress, and has one dayshift left.  I.E. 30 hour duration with 10 hours remaining
