Original title: Movie Maker Text Boxes

Having a problem. Created text boxes but for some reason they have reduced the time of the box to 00:00.1 and I can't amend it or delete it. The text boxes are on photos that last 3 seconds. 

When I hover the mouse over it, I'm shown what I typed in there, with that reduced time,  but when I click there I get nothing. 

Can anyone help please?
