Enter the Question - text is not changing

I am trying to make a couple typo corrections for a Spanish quiz...in the "Enter the Question" field...for example changing "is" to "si" and after making the change it reverts back to "is".  Another example, changed the word "have" to "hace" and it goes back to "have".  In the "Enter the choices" section, I can make changes and they stay.  Any idea why Enter the Question text changes are not saving?  Thanks
