Hi @Polymvth – really sorry that you weren’t replied to sooner!
I’ve just had a look and it wasn’t loading because it was a child page of home (which isn’t needed to be set). I’ve changed it and it’s now working as expected.
The jumping is caused because one of your showcase images is a lot smaller in height than the rest, if you fix that you shouldn’t have any more issues with it.
Hope that helps. I’ll look out for your replies.
