Door fitment problem, need advice!!!

[beZzZ]

I have recently found out that the passenger's door have a slightly bigger gap than the driver's door. ( please see the pictures )

I found out when doing a car washing, a few drops of water leak inside, not serious. Also, when driving on highway, the wind sound on the passenger side is more obvious than the driver one.

Don't really know what is the problem, need some advice. Like how's it's gonna be repaired and how much would it cost ( estimate )?

Thanks everyone in advance.
