Arrow sub menu too high

Hello,

I wanted to make you go back a little problem, we use for about a year now your plugin and never we had this problem.

In the left menu, when a link to a submenu the arrow is way too high and not in front of the links. https://www.zupimages.net/up/19/25/0ngk.png
Are you aware of the problem? Can you tell us when it will be repaired?

Looking forward to your answer,

Regards,
