Smoke leak from the front of my YS640

Hey guys,
I was grilling some burgers last night and during the cook, I noticed a significant smoke leak from the front of the smoke on the left side. The smoker was setup with grill grates, direct heat, 450 degrees and the meat was a 85/15 ground beef. I have included a picture. Is anyone using gaskets in order to seal up issues like this? Just curious.
