title missing on the first site of bp-fun multisite

I wonder how can I get page title showed correctly on index-page of the first site of bp-fun multisite. On all other pages title is shown correctly but on the first site index-page there is no title attribute whatsoever. Because of that the url-address is shown instead of title.

my multisite is located https://opiskelu.businesscollege.fi/konju
