How to get rid of the "ABOUT" me section at the bottom of my posts

Hi, i’m trying to see how i can get rid of the “ABOUT” me section at the bottom of my posts.

This section is really annoying and unnecessary and i used to never have it in the past but recently they’ve been added to all of my posts and I’ve tried to get rid of them for a while now and i just cant! Does anyone know how to get rid of this??

Its located at the bottom of my page just above the Facebook comment section. thank you so much
