There are two adjustable "stops" in the trunk area, one on each side that prevent the top from traveling too far forward which in your case, might be your problem. If adjusted favoring rearward, the center latch above the windshield is not achievable like you are experiencing.
There is a fine line between latching it tightly which pulls the top nice and tight, and latching it loosely which I found to present issues with fitment in other places. I replaced my top which took numerous tries for me to adjust the over-all fitment to my satisfaction. There are so many dynamics going on when adjusting the top. In the end, I favored "difficult latching". My wife struggles to latch it. I find it to be only a minor inconvenience.
This is one of the two "stops" I refer to.
