2011 Volvo C30 Driver Side door rain leak

[Pretribrapper]

Hope to get some guidance here. I have a small drip in my driver side door during rain and I am concerned it is coming in from where the upper door seal presses against the roof rack. On each side of the seal there is a small gap. Could that alone do it? I don't have the issue on the passenger side currently though which is odd.
Would a silicone spray simply be enough to help with the door seals? Any ideas would be greatly appreciated. Thx.

How far does that clamp go in? Is it causing the door to close a little harder? Could be forcing the entire door to close lightly so allowing rain to slowly seep in? Get some soft foam as in home insulation and put a small chunk to close the gap and see what happens during the next rain.

Could also be because the driver's door is just a bit looser overall from constant use compared with the passenger so only leaking on one side.
