Garage Door Weather Stripping [Stop water from running into Garage]

I bought "Jin&Bao Universal Garage Door Threshold Seal Strip, Bottom Weather Stripping Replacement Rubber Waterproof 20 FT Length" from Amazon.com, and in this video, I review the product and fully install it.
The problem I am trying to solve is we have been getting water even though our barn door is closed. In addition, during the winter snow has been coming through the bottom during the winter months.
If you are on the fence about this product from Amazon my hope is this video will help you out.
Thanks
Shawn
