Sorry, I have no more specific idea about what the problem could be in your case. When seeing such inconsistent behavior within a sequence of discretizations, I would try to verify the consistency of that sequence in simpler circumstances. For example, one could verify that the bandstructure evolves as expected as one changes the discretization length. A second possible check would be to do some time-independent transport computation. If you find an inconsistency already with these simpler checks, it will be easier to understand. If you do not, you have narrowed down the problem already.
