How can I change the position of the mobile menu in Catch Responsive pro

Hi all, I have added a plugin which shows Christmas decorations at the top of the screen on my website www.zhpv.nl. I am experiencing problems when viewing the web page on a mobile device. The mobile menu is partially covered by the Christmas decorations, and because of this it is not possible to tap the menu on a mobile device. I would like to move the menu's position down a bit but don't have a clue how to do this. Any help would be greatly appreciated. Thanks in advance. Regards, Andrew Huiskamp
