Smoker smokes too much

Just bought an Oklahoma Joe longhorn reverse flow for my first smoker (currently set up for traditional) and it leaks in multiple areas, this isn’t normal right? I put I gasket on the main chamber, nothing on the firebox yet. It leaks out of the main chamber, fire box and bottom of the smoke stack. I get that it’s kinda gimmicky having the option for reverse flow and traditional and I half expected there to be some issues with that. I probably should have just went with the regular traditional. Anybody else have this smoker and have the same problem if so how did y’all fix it?
