kinda hard to explain but I changed the front loader to baggage loader and the Aft loader to cargo.
That's the problem, you tried to use a cargo loader on a 737, which can't be done because:
- The 737 doesn't carry ULDs in real life
- The 737 cargo doors are too low to be reachable by the cargo loader
This was already discussed here:

If you want to change the airplane configuration globally, you should use the airplane configuration screen, not the parking customization.
The reason for having an option to the parking is to allow enough flexibility to have an airplane that USUALLY use cargo loaders, but if a specific parking is too small for them to maneuver, you can specify a different loader or no loader at all, on a specific parking, without having to change the airplane configuration globally.
Not that this would have made any difference: you can't use a Cargo loader on a 737, regardless how you configure it, for reasons explained above.
