Search Bar width on Header

Hi guys 5 stars for this brill Theme. I love it and the ease to change things.

Sorry if this is simple Q but cannot find answer on forums.
Im working on Staging Site (maintenance) so playing about with Settings and PreBuilts sites.

Using Christmas2 site the Search results show over 2 columns on demo.
I swapped Logo with Search and Flex layout remains as Equal Right & left.
My site only shows results over 1 column (iamge attached).
Q1. Should my site be exact same as demo?
Q2.Can I amend anything to make Search results same.?
Q3. How to increase width of theSearch Bar?
Thx Kenny.
