Post title two times

Hello!
On that page https://www.drphysio.gr/ on blog/posts section the post title appears 2 times and I cannot figure out why!
Thank you in advance!

Hello there,

I’d like to help. But when I visited your site, I couldn’t get a link to your posts page. Because I only speak English. Please share it here.

Regards,
Kharis
