There's no piece missing as far as I can tell. It's just the wrong weatherstripping. They just pulled out what I had and replaced it with what they had on hand. How do I find out what the right weatherstripping is? The house is 12 years old such that I'm not likely...
I'm thinking what this guys suggests in this video is the way to go, felt patch... y'all let me know if this sounds right.
