Can't change the language of the title Bibliography

Question

I am writing my PhD thesis. The entire document is in Greek with exception of some words in English while the entire bibliography is in English. The issue that I have is that the title of my bibliography is "Bibliography" and I want to have "Αναφορές" or "Βιβλιογραφία". When I change the language I have for title the Greek word but all the references change in Greek words and symbols. How can I have in Greek the title of the bibliography but not the following references?

\documentclass[11pt]{report}
\usepackage[english,greek]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{chemfig}
\usepackage{multirow}
\usepackage{graphicx}
\graphicspath{ {/home/Petros/images/} }

\usepackage{float}
\usepackage{mhchem}
\usepackage{lscape}
\usepackage{siunitx}
\newlength{\drop}

\usepackage[sorting=none]{biblatex}
\addbibresource{bib1.bib} 

\begin{document}

\foreignlanguage{english}
\printbibliography

\end{document}

Answer 1

A quick look into the manual of babel reveals:
\foreignlanguage{<language>}{<text>}

If you are using the correct commands, it works perfectly fine.

\documentclass[11pt]{article}
\usepackage[english,greek]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{chemfig}
\usepackage{multirow}
\usepackage{graphicx}

\usepackage{float}
\usepackage{mhchem}
\usepackage{lscape}
\usepackage{siunitx}
\newlength{\drop}

\usepackage[sorting=none]{biblatex}
\addbibresource{biblatex-examples.bib}

To LaTeX (προφέρεται 'λάτεχ') είναι μια γλώσσα δημιουργίας εγγράφων συνδεδεμένο με το
σύστημα αυτόματης στοιχειοθεσίας TeX. Ο όρος LaTeX αναφέρεται μόνο στη γλώσσα στην οποία
είναι γραμμένα τα έγγραφα, όχι στον επεξεργαστή κειμένου που χρησιμοποιείται για να
γραφούν τα έγγραφα αυτά.

\selectlanguage{english}
\printbibliography[title=\foreignlanguage{greek}{Αναφορές}]
