Double loop output

By inspecting your code, it appears those are two separate featured posts, rather than a single one with the author being duplicated.

The first one being: Is Marketing Operations The New Industry Buzzword?
And the second one being: Why The CMO Is The CEO’s Super-Weapon

This might be trivial – but have you double checked that you have the same author under the second post? Basically your code gets the author by display name. That then goes into get_the_title… for the life of me I cannot see why you’re doing that, rather than simply fetching the author object and outputting the image and other data via that.

See get_user_by()

Removed comment on how to output code.
