From the categories selection when chosen category is clicked you then are taken to the category chosen only you cannot see the default image for the categories title at top, this was before we made removed content and now it is not visible, there should be a banner on top row with the category image and centred wording.
The only way to see the category select it by looking at the URL
You are using a layout builder (Dashboard -> Layouts) for the “Shop” page, therefore you should use the “Page title” element in the layout builder to display it.
Seems that you edited the default “Shop” page, you should navigate to Dashboard -> Layouts -> edit the “New layout” and add there the “Page title” element (more detail in the below video).
