Needs Bug Repair

I’ve been using this developer’s “Abacus Lesson” which I’m very happy with. So I downloaded this app. Unfortunately, the ones and tens columns are frozen. The other columns seem to work. Once this bug is fixed, I will upgrade the star rating.

Developer Response
Thank you for using "Abacus Lesson" and rating this app! We apologize for any inconvenience. Digits that are not needed for calculation are intentionally prevented from moving. However, there is a possibility of a bug, so we will investigate it. Please wait.

It says to pass the grade to answer 10 questions but there is literally no question nor clue of what to answer, just a list of numbers
