I can’t tell if you need garage stop molding like others have said or if you need a tighter seal. There is a company called ThermoTrak, they have garage door tracks that force the doors to press against the frame to ensure a tight seal. Here are their tracks: https://thermotraks.com/select-size/. Your first step is the molding.
