Background Featured Image in Template Not Appearing

[luckybeecreative]

I'm looking for some help with troubleshooting. I created a post template and set a section background as an image with the position center center, attachment-scroll, no repeat, and size cover. When I created a post, it only shows part of the image and doesn't scroll (basically nothing that I told it to do). Has anyone run into this issue before? I'm using Elementor Pro with the Hello Elementor theme. thank you!
