Retraxone upgraded lock

Hello, I've got a Retraxone that is about 8mo old. Within the first month I noticed the passenger side would creep forward and then have a good sized gap from the tailgate, letting water in. I contacted retrax about it and tried their solutions. Still no luck. They gave me an option of upgrading to a pro at a pro-rated amount. Being it has Ithought I seen the Pro version had a latch on each side. But they tell my a passenger side latch is not available. Then I see a video of a Pro model. It looks like they've made an upgraded latch with linkage that goes across the cover to lock the passenger side. Can anyone verify this and take a picture of the linkage? I really don't want to dish out money on a new cover being the one I got is fine, just has

 

Curious about this since I was thinking of upgrading my trifold this summer with a Retrax. Before this, any water issues?

 

The only water issue I have is where the passenger side slides forward, it leaves about a 1/4"-3/8" gap at the tailgate. I'm still talking to them about other options. Because I don't want to spend more money (over $500)to replace my cover since it's less than a yr old, just for a lock. They have offered to sell me the rear extrusion the the lock linkage is Incorporated in to. But they think I wouldn't be able to swap them since my cover is one piece. Obviously they don't know who they talkin' bout. LoL Pretty sure I can swap them.
