Popbox Z value problem

I am having trouble with elements on my page coming up in front of the popbox. I have set the z value to 999 for the popbox section in elementor and set the z value of the image (the one coming up in front of the pop box) to 0. It did not solve the problem. Any advice on how to correct this would be appreciated. I’m not sure how to add a screenshot to this post.
