I’ve just noticed we seem to have two different versions of the search results pages showing - If there is a search result if shows the correct PRO header but just shows the title of the search results (these are just pages not posts).
Page with results - correct PRO header used across the site.

However if there are NO results it is showing the X header and NOT the PRO header which is quite a difference for users (although the page design for the search results actually look much nicer with the title for search results etc).
If there are NO results then we get this completely different page that doesn’t use the PRO header and seems to be using the X header - but actually has a nice page design with the ‘Search Results’ heading.

How can I change this to make sure the correct PRO header is showing on both search results pages (and they are the same layout) ideally with the title ‘Search results’ being shown on the screen that shows actual results?
Thanks
