This was Super frustrating for me to run into this situation. But finally figured the solution.
Solution was easy. It has to do with your Object Names. Look in my screen shot below. So make sure, your object name does not have all that extra text after it’s name. For example: div_Locked, and then it has extra text after this in my screen shot. So get rid of all of that text from each object name, and you should be good to go. Let me know if that works for you.
