W56 Base Station with 2 Handsets

[gyegavian]

I just got a W56P with 2 Handsets each registered to it own extension. When I look at the lines on the handset it shows the registered extension of the handset and the extension of the second handset, disabled. Is there a way to remove the second handsets extension from handset 1 & 2 from each of the handsets? I tried going into the Handsets in the web interface and only assigning for Handset 1, Incoming Line 1 and Outgoing Line 1 and for Handset 2 Incoming line 2 and Outgoing Line 2 but each handset still shows both extensions.
