Addon to point to sub-blogs - what could go wrong?

Hello, I am using Add-on to point posts from the main blog to the original posts in the network.

However, there is a problem in the theme I'm using (Magazine Premium) - there is a section, where add-on doesn't work and all posts point to posts on the main blog (all fetched by Autoblog btw). What could be the reason? Main section of the theme and even "Category" pages work perfectly.

I try to get support from Theme team, but any suggestions would help.

Best regards,
Milosz
