Steps to reproduce the issue

Go to smart search in the admin and create a new filter. Save the filter. Then choose Save as copy, to create a second filter with the same properties.

Expected result

A copy of the existing filter, which you can edit and save. With an unique alias like filter-name-2 of filter-name-copy

Actual result

I get an error that the alias is already being used and no copy can be made.

"Save failed with the following error: Another Filter has the same alias."

System information (as much as possible)

Joomla 5.1.2

Additional comments

I'm wondering why the smart search filter needs an alias in the first place…
