Hi Rob, thanks very much for your reply. Unfortunately I defintely do need to use periodic condition along the side-walls of my flow domain as I'm simulating a cascade of airfoils. 

Do you know why I would be experiencing the issue with “Automatic Compute Offset” not remaining disabled even when I un-tick the “Automatic Compute Offset” box and hit apply in the interface setup? Also, even if I can't stop “Automatic Compute Offset” from enabling itself, why would it fail seemingly randomly at some design points and not others? (the offset remains the same between the side-walls, only the angle of attack changes)
