It sounds like you may need to adjust the playground timer settings.

Once the lesson timer runs out, the Playground timer automatically starts counting down, even if the student is not going in to the Playground.

You may need to adjust your current playground timer settings to allow your student to access the Playground. You may change these timer settings through your Parent Administration page or by clicking on the parent icon on the student page (represented by two people standing next to each other), which allows you to change the default time settings.

Another thing to consider is that if they take longer on their lessons than the time that you have allotted for them, it will eat up their playground time. You may want to set their lesson time at zero. After they have completed their lessons, allow them to go to the Playground for their allotted time. That would prevent the Playground time from being used up.
