There is an important point to note with the if you are using the free Bodyweight plan, then your program will have a a finite number of week. The exact length of your program is determined by factors such as your sex, measurements and experience. This means that when you reach the end of your program, WAFFL will no longer create plans for you (unless you start from the beginning).
The solution would be to move to the Gym plan, which lasts as long as you want it to. The plan will constantly adjust, providing new challenges as you move along. Therefore, this does not have a end date like the Bodyweight Plan
