Newly installed doorwall leak

We had Reliabilt 3900 series Windows and door wall installed by Lowes on our house in March 2016. We have noticed water on the inside of the house in the sliding door track of the door wall after a rain. We have complained that we did not think that this is normal. Finally after awhile Lowes came to our house with a factory rep to look at it. The rep said its normal and it the design of the door to withstand high winds. He poured water into the track and said the weep holes are functioning normally. They left saying it’s installed and functioning normally. We still don’t think the design of the door should be dripping water from between the doors in the track on the inside of the house. (see video) We would appreciate some other expert opinions as to if this is normal or not from someone other than the installer or manufacturer who would defend both the installation and manufacturer of the product.
