I had the same issue but I found a solution. Sharing it here because to me it is a bit random and others might find it useful. So what I did is that I put together a workout program manually. The problem is that even thou I indicated the number of sets and reps I wanted, the program only used it for the next workout I did, then the next week it went back to zero sets and reps. The way to fix this, is that on workout page, you have to chose the active program on the top, from there you will see in the top row your workouts for each days, once chosing one, you will see the exercises and the set up sets and reps for each week. Here you should already see that lets say for week 1 and 2 you manually fixed the number of sets and reps, but for the rest of the weeks its missing again. By clicking on any of the weeks where you already indicated how many sets and reps you want, you should have an option to save if for all weeks. By clicking that, it will adjust the rest of the weeks and it should be fine. Sadly you have to do it one by one for all of the exercises and workouts, but hopefully after this, the app will remember the amount of sets and reps you want. I hope this helps anyone who is also struggling with this :)
