I have just acquired a 2.1 Slave Doser which is showing Firmware Version 1.34.
My other doser 2.1 which was a SA now running as a Slave is showing Version 1.36.
I have just tried to update the V1.34 doser to V1.36 but it does not give me the option of V1.36 only V1.34 and below. See photo
Is that what I should expect it being a Slave and the other being a SA running as Slave?

Thanks
