The regular export is preferred for LaTeX (C-c C-e l o) is preferred for LaTeX export as it generates the LaTeX cite commands. The version in C-c C-e r p uses CSL for the formatting, not LaTeX, and it allows you to get nicely formatted results without using bibtex/biblatex as the citation processor.

Hi, org-ref uses its own export engine which you call via (C-c C-e r p).
Please try that and report back if there are still issues.
