I'd think "take it back to the dealer". Maybe you're missing a part or its not installed correctly. No JK experience so that's my guesses.
But really I expect most of my off-road convertibles to have 'questionable' sealing mechanisms. My last jeep that had a top also had soft upper doors, seeing daylight between the top and the door was pretty much expected unless I was stopped at a light.
Odds are im typing on a tablet. It takes too much effort to add some punctuation. Im lazy, get over it
Never underestimate the power of stupid.
