Hello, @danny,
1. I have set the conditions as shown in this screenshot: https://postimg.cc/3dgHq1Rd and now the header is working fine on the home page, please check this screenshot: https://postimg.cc/nsNRp8SZ
2. That search is Custom Text and you can change it from the header builder by editing the search widget as per your requirements: https://postimg.cc/yJhj4JRh
