If you could attach your entire file, I'll be happy to try to help you. There seems to be something else going on--I don't think the liftarm in the previous step should be faded when attached to the wing assembly.

For the record! I totally forgot to update this thread...
The solution is quite strange, but the only problem is that the submodel did not have the ".ldr" extension! I used Stud.io to generate the .ldr export, and by default, it does not add any extension to the submodels inside the ldr file... so when you create submodels in Stud.io and you plan to use LPUB3D, keep in mind that you have to add the ".ldr" extension manually to your submodel's name.
Then everything works as expected...
