I have the following problem. I am writing a thesis where I want to have separate bibliographies for each chapter. To this end, I use the chapterbib package with sectionbib option. The references in the main body are fine - in the form of [14] - but in the Bibliography section for some reason nubering is changed to letters. This problem does not appear when I remove sectionbib option. What I want is getting rid of numbering entries in the bibliography by letters and have it consistent with the main body, i.e., in the form of [14]. Here is the MWE (I'm including the whole preamble, as I never know what might matter):
