Triangle error in the vertical meu

Hi at all,
I have some problems with the triangle in the vertical menu of maximenu ck. I have changed the "Title style" color at "Main menu"->"Menu bar" for normal and hover, but the triangle is still white and in the right corner there is the new text color. Take a look to the picture.  In the submenu everything is fine with the triangle.
Kind Regards
Markus

Hi
Please give me the url of the page where I can see the problem

Hi Ced,

jgs4.jacob-grimm-schule.de
You have to write it twice in the URL, because IONOS or my htaccess are making problems.

Kind regards
Markus

I'm coming to an old website, I don't manage to go on your website using Maximenu CK ...

Hello Ced,

you have to call up the website twice.

Kind regards
Markus

not sure why but in Firefox it did not work, I could see the issue in Chrome
go in the styles options >> layout >> set it "vertical", then save the styles and tell me if it fixes it
