Red borders appear for no reason

I’m making a parallax effect with the image in the background, but does anyone know how to fix these red edges?

Hey Jeyner,
Thanks for reaching out to the community. Can you please clarify that you would like to remove the red edges? Is it showing in your design view or only in the prototype?

Would you mind sharing a copy of your file? This will help the community to reproduce the issue. Thank you!
