Hi Patrick,
Would you please do a test for us? Please go to WordPress Dashboard > Appearance > Menus and change the position of the Kontact
and Über mich
menu items. I want to know if the problem is that specific menu or the position.
If the problem is position, please add an extra section in the page using the Pro content builder and add sample text there to make that section grow in height. See if it helps.
If the problem is that specific menu, please try to add another menu item and change the ID to something else and test the case.
kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case if you still have problems.
Thank you.
