VOIP-108664 in 5.4.2, now I have 2 directory keys...

When I update to 5.4.2, the phone now displays 2 directory keys.  Looks like 'fixing' VOIP-108664 causes this as <=5.4.1 doesn't do this.

I have the following config 

softkey.6.enable="1" 
softkey.6.label="Directory" 
softkey.6.action="$FDirectories$$FSelect$"
softkey.6.precede="1"
softkey.6.use.idle="1"
softkey.6.use.active="0"
softkey.6.use.dialtone="0"

but if I remove this, the config WONT show it for <5.4.2 devices..

I can't find much data on this VOIP-108664 issue or how to work around this.

Thanks.
