WhatsApp and Telegram icons not showing

Hi Carolina,
Hope you’re well.
Firs of all, I would like to thank you for your buetiful Deejay theme. I am creating a website for one famous russian sound editor using your theme.
However, I have some difficulties with social menu panel: WhatsApp and Telegram icons are not showing on desktop – just pictures of chain link, in spite of the fact that the icons of Facebook, Vkontakte, Instagram are showing correctly.
Can you please help me to make Whatsapp and Telegram icons visible.
Thank you in advance.
Elena
