'Blue' troubles – Cars and Trucks: preschool toddler learning games, learn shapes & colors Review

My toddler really enjoys this app. As someone said earlier it doesn't progress much but is still a fun app. The only issue we've had with it is when it gets to the 'blue' stage the letter 'U' is missing and we can't go forward or backward. Could you please look into correcting this? Thank you.
