After replacing the rear shoes, hardware, and cylinder one of the shoes is getting pushed too far and will not go back down?

It sounds like you got the brake shoes mixed up, there is a primary and secondary shoe and if you have it in the primary position the brake shoes have a hard time releasing. Here are diagrams in the images below to help you see how to do the job correctly, also I have marked the primary and secondary shoe which has more lining than the primary shoe.
