Product defect (TF00696517).
The problem is that when you import questions with apostrophe/single quote (‘) with bulk import modules they produce different hash code that the questions created in UI. Possibly they escape apostrophe using other methods, or do not escape it at all. It is clearly visible in "QPM.UI.User.MVC_AD_...log" if you compare questions and hash of the question between user profile and MP setting:
<d2p1:Value>What is your maternal grandmother's maiden name?</d2p1:Value>
<d3p1:Value>What is your maternal grandmother&apos;s maiden name?</d3p1:Value>
This Product Defect (TF00696517) will be fixed in a future release of the product.
