This seems strange, I would have thought that in https://bugs.eclipse.org/bugs/show_bug.cgi?id=531132 we have fixed the cleanup issues. Is it possible that the AutoQuickFixTransformation does something non-standard here (not part of VIATRA)?
Also bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=543789 is highly related.
