If you want to show the product categories, you need to create a menu in Appearance > Menu. You can enable product categories in the Screen Options in the right top corner (they may be disabled by default) Then you add this menu in the Mobiel Menu in the mobile view of the header.
sadly this did not answer my question. I would like to have the default look (https://prnt.sc/1ue4r09). But after i changed something on the categories tab it looked like this (https://prnt.sc/1ue5610).
I just wan´t to get back the default look. But how? Changes are shown in the documentary does not affect to these things.
