The toolbar displays item several times after edit content

I have a small problem with the toolbar, when I save content I see a new item in toolbar.

I don’t know where this problem comes from.
Does anyone had this before?
Thank you for your help

@Thibaud That’s very unusual - I’ve never seen that before. Especially because the “More” menu is for small screens.

What versions of python, django and django-cms are you using?

I’m using python 3.9, django 3.2 and django-cms 3.11.0.
To be more specific, I’m trying django-cms using this git GitHub - django-cms/django-cms-quickstart: A Dockerised django CMS project, ready to deploy on Divio or another Docker-based cloud platform, and run locally in Docker on your own machine. A Divio account is not required.
