Thank you for the response.
I am not sure why it was happy with K->L reversed on one of the sensors either.
I did send an email to Emporia support right after posting here on 3/3 but I did not get a response as of today.
I went ahead and bought the flexible 200A sensors and installed them around the bus bars (between the main breaker and the circuit breakers). It was a bit more work/more cables but it is working flawlessly so it was worth it.
Thanks again for the response, much appreciated!
