I noticed while working on my hatch the other day that the wooden piece under the rear of the sliding hatch is bent so that the ends where the screws attach from the top have about a 3/8" space. The middle looks tight . Just the ends are bent out. Is this normal ? If not what can I do to straighten this out or at least solve an issue with leaking. I've siliconed both sides of the screws as best I could but don't think this is the permanent solution. Thanks
