Steps to reproduce:

1. Open the attached project
2. In the Search window, add an And operator
3. Add a second And operator
4. Observe the search query

Actual results: And operators become invisible after adding the second operator. They are still present if the query Builder mode is disabled. The missing right-hand operator error is also displayed

Expected results: And operators remain visible after adding the second operator
