Steps to reproduce the issue

In Joomla 4.x setup a filter:

Smart Search > Filters > New

Add a title (Test 1), toggle the relevant content maps

Click 'Save & Close'

Setup a new Smart Search > Search menu item and select the above filter.

Run through the process again, but this time add a different title (Test 2) and toggle a different set of content maps.

Index the content.

When going to the frontend, the 'Test 1' search menu item will return results, but when going to the 'Test 2' item no results will be returned.

Expected result

Both should return a different set of results depending on the content filters.

Actual result

The first result works but the second search doesn't and it includes "&f=2" in the URL. If this is removed, then the search results are shown.
