Howdy,

Looking at the full Console output you enclosed before (better to attache a file with it if needed) it appears the latexmk ran bibtex as requested. I wonder if you used backend=biber at one times and didn't clean out the special files that biblatex creates for its use so biblatex (that is where the report is coming from) is getting ab it confused.

Good Luck,
