sorting and labelling based on main bibliography (not dfgprojpapers)

[romangrothausmann]

When using numericcites (and biber), I noticed that sorting and labelling/numbering is based on the first bibliography generated by \dfgprojpapers, such that the sorting of the main bibliography (created by \printbibliography) is then not numbered consecutively. It seems to me that this depends on the initial creation of the *.bcf file. For example as a dirty hack I get the desired sorting when I first comment \dfgprojpapers, build and then uncomment again and build again. It would be great if that could be done in a more sophisticated (latex) way.

Sorry for the late answer to this issue. I have been stuggling with this, and in the end running make -B sufficiently often solved the problem.
Do you have any suggestions what/how to improve this?
