Logo editing/removal issueBrowser Info Environment
I'm not the theme developer, but if you want no site name in the top left corner go to Dashboard > Stacks and click on the Site Name stack. If there are any blocks there, remove them. Add a Content block and Save without adding any content. The block you just added will be represented by an empty, very short rectangle. Click on that and choose Custom Template and enter "My_Site_Name" (without the quotes) in the Block Name field. Click Save, then click Approve Changes. Now you should have no site name up there.
Hope that helps!
