Dear Wolfgang, it was indeed frustrating, took me a while to detect the section, where it starts to break down. But it is what it is.
But in the meantime i recompiled the library and it looks good now, what a relief! Compared the results to the reference I have and it's matching now. Thank you a lot for the solution, good that this forum exists!
