Raymarine Axiom Oil Pressure Duplicates

I have a Raymarine Axiom which receives data from an AlbaCombi. I am using SignalK with NodeRed to estimate the fuel consumption from the RPM of the engines (on the basis that this is a better way of doing it than me simply noting in the log the RPM and an estimate of fuel usage) using the published fuel consumption curve. Now the strange behaviour is that when I use the SignalK - NMEA2000 plugin and map the calculated value back into an Engine PGN the oil pressure on the axiom flips between (at startup) 70 PSI to 0.7 implying that somewhere in SignalK something is getting confused. When I disable the SignalK to NMEA2000 plugin the Axiom stabilises at the expected 70 PSI. Any ideas?
