V 3.5 – unexpected displaying of the main menu

Hello guys, i updateted the theme Catch Evolution Pro from 3.4.2 to 3.5 and i recognized, that the displaying of the main menu has changed. It appear a little box named "Menu" on the first menu button (Home) and there are strange small silver dashes in the below part of the main menu. At least, the menu is also more higher than the old one. Please, take a look on www.astrolive.ch . Have you got an idea what's happens? WordPress Version: 4.9 Theme: Catch Evolution Pro Thanks a lot in advance for your answer. Bye Ernesto
