Rugged Liner Tonneau cover guidance

I purchased a Rugged Liner premium hard tri fold cover. I am having issues trying to get a full seal around the bed. I tried to follow the instructions but they are very vague. There are two openings, one near the driver side and one passenger side of the back of the cab. I have tried resetting it over an over with no luck. Was hoping anyone with the same cover would post additional pics showing it installed. I am using the prefab blocks in the bed rail and with all latches secured I am told the four latches should be 90 degrees to the bed rail however mine are more canted at an angle. Apparently I have stumped the people I purchased it from and they have no clue and refer me back to the directions.

 

You will always have a little bit of a opening on those two points. I use to worry about it with my
tri fold hard cover. Not anymore.

 

Thanks for the reply. My OCD is just driving me crazy about it.
