Back end code appears on front end

[Boregard]

Hi all, I downloaded the new version of a theme and in my header title I see this now (see image). I’m not sure how to change it. Can someone walk me through how/ where to change this? I have tried the following:
Appearance section: customize tab
BeTheme section: Fonts tab, Size and Family

See site: https://www.lllogistics.nl

I think if you setup the logo for your website from theme options or Appearance => Customize the issue will solve.

otherwise how to contact an author to get support or for any technical query:
