"No Title" When sharing homepage on Social Media

Hello there, guys!

So I started working on my first website and tweaked a whole lot of settings. I am running the “ColorMag” Theme and I created the entire website and finished with it a few minutes back.
I was going to launch it on Facebook, It showed “No Title” for the homepage. I want the website title to appear.

The site identity is in order and there isn’t any code in the theme php that forces this issue.

My Website – > Comic Addicts

I will also add a screenshot of what I am facing, please find it here

Thanks in advance for anyone who tries to help!

Cheers! ??
