First, you are using an unsupported airplanes without having a profile for it, which will never work in GSX. You don't say if this happens with other airplanes too but if it does, is it possible you might have manually copied the whole GSX packages to the Community folder, instead of having Symbolic links to it ?
Doing this will guarantee nothing will work because, the manually copied copy in the Community folder will be left outdated (the FSDT Update only updates the Addon Manager copy ) and will prevent the sim to see the copy that has been updated. If you did this, manually remove the copies you made in the Community folder, start the installer and click "Relink", so it will create the Symbolic links as it was supposed to.
