Thanks for letting us know about the issue. We'd love to help you with this.
TemplateToaster allows you to show or hide the logo and provides the option to set different widths and heights for the logo for tablet and mobile view. If you want to use multiple small logos on your header for the mobile view then you have to set the same for the Desktop view. We hope this is helpful. Let us know if you have any more questions, comments, or concerns.
