So I had a new liner install completed. Very happy with everything overall. Next day, I Went to check out the top termination and notice what looked like a starter hole/ slice where they were going to cut the liner at the top, but then abandoned it and cut just above. I've attached a pic. This is a heavy wall liner and I'm guessing that being so high up, it's a non- issue. Would this impact draft if left as is? What do you all think?
