Hi, There's a couple of things wrong here. The main thing is that you've introduced a short section of triplicated highway. (If in iD editor you zoom right in then select the traffic light or the crossing node, move it to the side a bit, you'll then see the triplicated section of highway, Way: High Street North (154545583), Way: High Street North (742478357) and Way: West Street (139387027) in the same position atop each other.)

The crossing node is tagged as uncontrolled;traffic_signals, what is it uncontrolled or controlled by traffic_signals?

Note that there are several relations involved at this crossroads making for difficult amendments. The best amendment would be to remove the central traffic light note and map all the individual lights and relations. This could leave a central node tagged only as a crossing point. In any case the replicated section should be removed.

The simplest but rough solution is to join the crossing and traffic light nodes, thus removing the triplication. remove the crossing tags from the node which actually are not needed as you have the footway tagged as a crossing.

What do you think? 
Regards Bernard.
