I see the same water running from under the rubber seal on my windshield as well (2015 Windsport). So far it doesn't seem to be causing any issue. I see that the seam in the rubber seal is at the TOP of the windshield and although I don't know for sure, I suspect the seam should be placed at the BOTTOM of the windshield instead. If I'm right, water enters the seam and runs down inside the seal.
