How can I delete the 'related projects'

Hello - I have a problem with my project page layout and cannot find solution in the wordpress jetpack support forums. It shows ‘related projects’ twice in two different formats, and the author. I would like to delete all of this and just show the project title, image and text description. How can I delete (CSS?) the three bottom sections - see screenshot:

Any advice would be greatly appreciated!

Hello there,

I hope you are doing well today.

You can use the following CSS code to remove these elements by going to Appearance > Customize > Additional CSS and pasting it there.

/*Remove elements*/
.author-bio {
    display: none;

.shapely-related-posts {
    display: none;

Best Regards,
