Still cannot remove after_section element

Hello. I have created a page using the Avia page builder. On the front-end is a section with the ID of av-layout-grid-1 and class:

av-layout-grid-container entry-content-wrapper main_color av-flex-cells avia-builder-el-14 el_after_av_section el_before_av_layout_row submenu-not-first container_wrap fullsize

This element is empty (it only has a few empty <div> elements inside), but a height of 60 px on desktop and 120 px on mobile (screenshots). This is not an element that appears in the page builder on the ‘edit page’ screen. How can I remove this element from my page?

In a previous ticket, I raised the same issue about a similar element on my page. In that ticket, and agent suggested that as a solution, I can re-locate color elements on the page, save the page, then re-locate the same color elements back to their original location, and save again. I tried that in this case, but it did not resolve my issue.
