About EV3 master programs (urgent)

We have created a Myblock for each of our runs. Then we put all of the MyBlocks into one program. Each of the MyBlocks is separated by an EV3 button block so that when the button is pressed, the next program runs.

But it is not working. After one of the MyBlocks finishes, the A motor is getting locked, which is the problem.

The problem is that we are unable to change the position of the A Motor to set it in position for the next run.

Can you please tell us what we are doing wrong. We are going to the MA State Finals and are stumped.

Thanks
