With the tab in design, when the header channel is mounted into the windshield, the tab on both sides of the jeep flip down and into slots located on the door surrounds.
But as I said take everything apart except the header just so you can either tighten the latch screws at the footman loops. This could be an area where if you or the shop/suppler mounted these latches incorrectly could instead force the header channel back and away from the windshield which seem to be what has happen.
Once you get the latch points on correctly (assuming they can be removed flipped/adjusted) you would then latch the header into place more forward then what's being shown in your images.
Once you have the header in place and latched down, goto the rear of the jeep and pull the soft top back toward the tailgate. Applying some down force on the rear of the soft top frame, flip in the plastic tab on both sides of the bed rail corners.
Then toss up the side window and locate the zipper, get the zipper started, then line up the door edge into the door surrounds. Zip the window down and into place on the soft top. open the side door and fit the side window edge (plastic molding) into a slot on the surrounds.
Once both sides have been zipped in and down and the forward window edge has been tucked into the surrounds. You can flip down the window's lower edge into the bed rails. attach all velcro edges at this point.
The last thing one does at this point is to fold down and flip in the tab ins (above the door edges) into a slot on the surrounds. If there's no edge or slot that these tab fit into, it is possible that you have a tab in design soft top with a channel designed surround which wont work.
Ideally, because you attempt anything I've said above, you will need to see if your tab in will work with your surround design. if not you'll either have to return the top for the correct version or locate the correct surrounds.
