Please help! ALL Modern pages impacted | SharePoint spacing issue

Mark-Kashman - Thanks for your reply. 

The issue has now come up in another area. The space under the Hero web part is now increased to 24px. I think they restored the missing space and added this extra space below the Hero.

Find attached the screenshot.

Please help with this issue. There is way too much space. Again it is not visible on edit mode and only appears after publishing.

HERE is the CSS causing the issue:

@media screen and (min-width: 641px)
.CanvasComponent.LCS .CanvasSection--read.RestoreLostMargin .ControlZone:last-of-type {
    margin-bottom: 24px;
}
