3D Extrusion Splitting Into 4 Copies
I'm trying to follow this guide (timestamped to part I'm on) to create a custom version of a tv show's logo and when I go to create a 3D extrusion from layer instead of getting what I see in the guide:

I get my picture split into 4 copies zoomed in on the corner:

Does anyone know why this is happening and how to get what happens in the guide to happen for me?
Thanks for your time!
Stephan
