It seems on the plane editor the doors are all set to ignore warning and doors work correctly on 737 but not on 738.
Nowhere in your default configuration for the 737 we set any doors to be ignored, they are all set with their proper codes, except the ones which are INOP in some variants, but they would show as DISABLED ( "No door at this position" ) not IGNORED ( "doors with no open/close checks" ).
If you have doors that shows ignored, it's because you configured them like that, so you need to remove your custom configuration with the RESET button and be sure the airplane editor shows "using internal database"
