Part of the missing subcategories on mobile version

Hello,
I contact you because I encounter a problem with the menu I created with Ocean.
In the mobile version menu, I miss a part of the menu that I have of course on a computer version.
I go to the “Food supplements” section of the menu but I miss a part I have on the computer version.
Do you know what it could come from?
My site is https://plantaromazen.com/
Thanks.
