Owner block displays duplicate enteries

Can anyone tell me why my 'owner_block' under 'groups' is displaying 'Subscribe to this group' twice ?


It's not plugins code doing it, as it works as expected on a fresh 1.7.1 installation.

Therefore it must be an error in my 1.7.1 code.,

My 1.7.1 installation is still based on a 1.6 theme, was there any updates that you needed to doing to your theme, which I've missed ? 

-> I tried the information here about copying over the /elgg/view/default/js & page_elements directories, this doesnt solve my issues.

Are there any others that I'm still missing ?

Theme that I'm using is 'Elgg example theme framework'

Many thanks, for any help..
