RPM - Not Working with ESC telemetry RC2

Hello, I just tried the Helicopter 4.1 RC2 and the RPM seems to be NOT working.
I am looking to have the internal Governor implemented by following the Esc1 Telemetry. When setting the RPM parameter to follow the Esc Telemetry, I am not able to see the rpms in the status for the RPM, but I can see the Esc1 rpm data in its status. I am using a MatekH743 and Blheli Tekko32 F3 Metal. Everything else so far is working fine! Thank you.
