I am using these packages:
\usepackage[english]{babel}
\usepackage[round, sort&compress]{natbib}
\usepackage[ sort&compress]{natbib}
\bibliographystyle{dinat}
However I am writing in English, but the template is German.
I changed all german language stuff to English.
And I know that dinat is a German citation thing.
I even tried to change the dinat.bst file, but failed and nothing happend.
dinat, whereas the one you've referenced uses the bib stylenatdin. This matters quite a bit. – Mico Sep 02 '19 at 09:29
