fill in the blank - not showing button when all answears are correct

Hello,

I found out that when users fill all the blanks correctly they don't have chance to start it again. There is no button "try again" even if it's checked in the admin. When I make a mistake once I can see the button "try again". Could you tell me is there any solutioun to add "try again" button even if the question is 100% correct?

I use fill in the blanks (not question set).

I'll appreciate your help :)
