VVX 501 will not show redial icon in home screen.

Hi ,

I am working on upgrading our Polycom VVX501 phones and noticed that the home screen Redial ICON disappeared when upgraded to 5.7.2. I tried upgrading to 5.9.3 and still dont see the icon. 

Phone InformationPhone Model VVX 501 Part Number 3111-48500-001 Rev:A MAC Address 64:16:7F:02:16:4E IP ModeIPv4IP Address 172.16.30.32 UC Software Version 5.7.2.1277 Updater Version 5.9.2.1208

I have even tried using the below config but still no joy. 

homeScreen.application.enable="0"
homeScreen.BToE.enable="0"
homeScreen.calendar.enable="0"
homeScreen.directories.enable="1"
homeScreen.doNotDisturb.enable="1"
homeScreen.features.enable="1"
homeScreen.forward.enable="1"
homeScreen.messages.enable="1"
homeScreen.newCall.enable="1"
homeScreen.redial.enable="1"
homeScreen.settings.enable="1"
homeScreen.status.enable="1"

Has anyone experienced this before.

Attached are the logs from the phone with config logs set to debug and pbu file from the phone.
