Problems with the "General Stress-Deformation" Interface for external materials

Hello,
currently I'm trying to use the external material with the "General Stress-Deformation" type interface. I created all the arrays as mentioned in the "Multiphysics Manual" but I always get the error message "Error in multiphysics compilation. Tensor index out of bounds" which may be related to the interface.
Some informations regarding the material model and the code:
I'm writing in FORTRAN and using the intel FORTRAN compiler with the BIND() command so the code can be read as C. It already worked for the "stress-strain" interface so I don't think this should be the problems root.
I need two sets of internal state variables (or one combined set but I prefer two).
The current COMSOL model is just a simple cube with one element and tension load as recommended.
I attached the model as well as the FORTRAN sniplet and the shared library (for LINUX). If you want to run the simulation you need to re-import the shared library. If you have any solution or advice about modeling in COMSOL please share it (it's my first time using COMSOL). Thanks in advance,
Paul Löps.
