Bracket links (like <<link>>) create a \texttt{} \hypertarget{} pair

explicit \label{} \ref{} in the org file ?

The \texttt{} is probably because org could not resolve a target from your link. I can't help much with your problem, but see

C-h v org-latex-link-with-unknown-path-format RET

for an idea of where the \texttt{} comes from.
