Return of power to Pi during shutdown sequence module

Issue: When the main power to Pi is lost then the Pico takes over and shuts down the Pi at the set time. But then it takes about 60 seconds for the module to shut itself off. If power comes back during this, the Pi wont restart. 

I'm reading that this is a known issue but I can't find a solution anywhere. Please help.
I'm using the the 0XEC firmware version.
