studio theme header image is not left justifying

I did see one answer re issue in forum, however, I don't know how to use the answer to solve my issue.

I have loaded a header image that I want to go from left to right on the site. It appears to be centering, instead of left justifying.

The site is one of my multisite sub-sites. I can't leave it up for long, so I am enclosing a screenshot

Thanks in advance! Linda @iempoweru
