Just following up on this thread. We have now released the previously mentioned updates to the 'Your top trades' feature.
This update means your 'Pending' invitations no longer show up in the list of trading partners in 'Your top trades'. This feature now only show friends and family who have joined AGL Solar Exchange.
Your pending invitations are now visible via the 'Manage your invitations' link below 'Your top trades'.
Hopefully this addresses your feedback.
