menu is overlaid on top of the content on all category pages

the menu is overlaid on top of the content on all category pages. As a result, it crops the top of the content of the store (filters, sorting of categories, etc. which are therefore invisible). I searched everywhere in the settings and impossible to find how not to have it cropped. This menu is by default on all pages. On the product page, it is a separate element above and not superimposed like on the category pages. Thanks for your help !
