You don't say which airplane you are using if it's supported by GSX and if it has a GSX profile.
In any case, you can decide which containers are used by each airplane in the airplane configuration editor. That is assuming you are using an airplane that is not already supported by GSX and/or have downloaded a profile and/or made one by yourself.
If you are using an airplane supported internally by GSX, and it's loading the wrong containers for its type, we would like to know it, so we can fix it.
