LoPro gap on cab side

So I've had my LoPro tonneau cover on for the life of my truck so far (1 year) and love it. It keeps most the water out and does a great job of keeping my bed useful year round. However, the front edge of the cover (the cab side) isn't sealed very well and snow melt still occasionally gets in through these gaps in the corners. Is this a common problem? Is it how they were designed? If it is a common problem, what are some common fixes? The cover does such a great job that this minor issue is really annoying! I'll try to take some pics tonight when I get home but want to hear from you!!

Thanks guys!
