Upload Image modal appearing behind menu using Avada Theme. How can I change location?

Distance from top or z-index would be fine but I can’t seem to control them in the cssfiles.
ap-modal is the class indicated when I inspect the page and editing this on the page does result in the appearance I want but when I edit

/wp-content/plugins/anspress-question-answer/templates/scss/modal.scss

the changes are not visible.
I do not have a cache plugin running and I have flushed the cache in both chrome and firefox.
