Unlimited hours not adding up

Over the weekend I noticed that every time I reached a prize with unlimited lives the timer only gave me what the prize was.  So if I reached one but still had over a hour left when I reached the next 2hrs, the timer only said 2 hours. The hours aren't adding up.  I got all 5 prizes in one sitting and should have had more that 10 hours of time in total, but the timer only showed the final 6hrs.

Also, I played Bubblegum Hill yesterday and won over a dozen times, but each time I won the timer only reset to a single hour instead of adding up.  This occurred even when there was 50 minutes left when I won.

Additionally, I don't know when this started but turning off my device no longer stops the timer from counting down. That seems unfair for the time to continue when the game or device isn't running.

Help and please fix!
