NI cDAQ-9185 Watchdog Expiring Even Though Reset Command Sent

I need to implement the Watchdog Feature on a cDAQ-9185.

I'm using the following code to reset the watchdog (which configures correctly - or at least without fault). The watchdog timer is set to 20 seconds for testing. After approx 7 seconds, the below Vi begins executing every 0.1 seconds, however the c-DAQ still times out. The below Vi also reports correctly that the watchdog timer has expired and fails my system.

Here's the code I'm using:

Is there something I am missing? I've also ensured that there is no error on the error wire, but there is a warning (which is a Uninitialised Shared Variable warning, but it shouldn't cause an issue?)
