Space under slider

The image slider at the top leaves a lot of space underneath the slider. This issue was reported before and I tried the privious solution. I tried the “Check to make slide Full Viewport Height” ckeckbox, but when activated it displays the images wrong. When deactivitaed it leaves the space below. It seems to be only at the first load and it goes to the right stage at the 3rd slide. Can you please help me to fix this issue?
