Leaking into body of door

Not sure if I can keep these. They seemed to fit well but we had some rain recently and I am finding that water is leaking into my front doors. I made sure that the front tabs are not in the channel, they are supposed to funnel the water away from the internal door structure. I also think that they sent me a used set of rain guards. They were scratched up and looked like they had been handled quite a bit when I got them. There was no adhesive in the packaging so I am not sure if this was just an old model that they wanted to get rid of.
