Bug: third level menu aligns wrong and is not clickable

Hi,

I have a navigation menu with a third level, but these are not aligned properly. (example: food / vegetable / patato), the third level aligns to the top instead of next to the option. So if the second level has 5 options to click on, and the fifth has two variaties, these are aligned next to the first option instead of the fifth and can’t be clicked on.

Example can be seen on https://www.emotieanticipatie.nl . Click on the second menu option ’emotie anticipatie’ and then the last option ‘vaardigheden leren’.

How can this be fixed?

Greetings, Ruud

ps. I use the meris theme 1.1.2
