Beko electric oven door seals

Just bought a Beko electric double oven cooker from Argos.Both of the oven door seals are not fixed to the door all the way round the door. They appear stuck along the top of the doors and part way down the sides but are loose the rest of the way down the sides and all the way across the bottom of the door. Is this correct or should they be stuck in place right around the doors.
