Thanks for your help. I figured that it was the incorrect scaling of the
eigenvectors after I transfered them to the finer mesh.

You need to explain in a bit more detail what you do and where the problem
happens:
- Do you compute the eigenvalues on an adaptively refined mesh? If so, are
they correct *on this mesh*, and are the eigenvectors?
- If so, I understand that you transfer the solution to a different mesh where
things are wrong. When you visualize the eigenvectors, do they look wrong?
How so? Only at hanging nodes?
You should be able to test this on a coarse mesh.
