Dear @Des
Do you have any third-party plugins installed or CUSTOM JS code? Is it possible to deactivate it for a moment to see if the problem remains?
Also you can use a different layout for mobile.
Have a look into that.
Best!

Dear @MargauxLallart
sorry for asking more.
So, when you are inside a project, you want to modify the arrows which can switch between the project in the same category?
Best!

Ex in LAY, add/remove a CSS class on the 'index' : https://kiti.ca/kitty-care
Doesn't work as well on mobile... working on it.
