Issue adjusting bottom panel

Hi all, I am having issues with the size of the bottom panel when viewed in preview mode. I have attached a pic so you can see what I mean. When I view my site in preview mode, the bottom panel is higher than I would like. I have tried dragging it down in editor, but it makes no difference. Really appreciate it if someone could help. Thanks, K x

hey, @kerry-aristidou
Please see how it will work for you:
