yeah Elementor updated there flexbox. If you select the 2nd Column in that top Section, theres the Inner Section, you need to give that a Mimimum Height to fill the space.
The only thing is the text for the image is now coming at the top of the page (see above “Charles Bold, CEO Bold”), whereas in the demo it comes out at the bottom.
In the Column > Inner Container i believe there is a vertical alignment option – which should allow you to set the content tom the end ? Sorry bit rusty with Elementor.
