PTP 550 Watchdog Feature

I'm trying to enable the watchdog feature on a PTP 550 running 4.4.2. When I try to save the config I get:

Configuration save failed.
Config ID
Reason: The configuration was obsoleted
Configuration save failed.
Has anyone else seen this?

I've noticed this error too, but when trying to set other features. Usually a reboot of the radio gets rid of the error and then I can save.

Hi all,

Could you please try 4.4.3?

I don see the issue with 4.4.3.

Thank you.
