Add more fields in Advanced search is broken

[HonkXL]

The "Add more fields" feature in the Advanced search is broken.

In earlier versions it was possible to enter search terms for the "more fields", but now I can choose a field but can nowhere enter the search term for this field.

See screenshot. Here I entered a name. Now I want to add a field and search for this. But I can not enter anything.

Admittedly not very intuitive but using the demo setup and clicking the search button after selecting the new field, the page reloads with the field in place which can then have a value added and searched for

Thank you for your answer. Yes, it works this way, but this is not intuitive.
Best solution would be to change it to reload after selecting anything here (and preserve things already entered in other fields).
Other way would be a short info text about this.
