The "home" button of a new blog is redirecting to the blog template homepage

Hello,
I created a blog template with a custom menu which includes a "home" button.
The problem is, when a new blog is being created through the "New Blog Template" plugin, the "home" button in the menu of the newly created blog links back to... the home page of the blog template (instead of the home page of the newly created blog).
Could you help fix this issue?
Thanks in advance for your help!
