Yoast Open Graph Homepage

My website is https://www.marketingartgallery.com

When I try to share https://www.marketingartgallery.com, what gets pulled into facebook is not what I specified in the social/facebook tab of the app.

It pulls in info from the posts on the home page along with feature pictures.

Not sure why this is happening or how to fix this.

I use the sparkling theme from colorlib.

Thanks for your help.
