This is normal behavior for the HSC register.
Continually copy the value of ML 1 to another register. On power-up, copy this last value to the actual HSC register.

I am happy to hear that because I'd like to downgrade all PLCs at this moment until Unitronics comes up with a more stable firmware.
Maybe I will try a downgrade on another PLC. Right now I am still waiting for a reply from Unitronics to my support ticket.
But many thanks for sharing your experiences.
When I turn on High Speed Counter (input 0,1) - type set to AB shaft encoder x2 and set the operand to ML 1, the values store in ML 1 is in order. However, once I switch off the PLC and turn on again. The value in ML 1 reset to zero. How could I retain the value after power down?
