openHAB 4.0.0.M1 - IAMMETER binding has mixed up the channels

Channels are mapping to the wrong values

Eg Current gets the voltage including the units (which are not provided by the device)

15:52:00.427 [INFO ] [openhab.event.ItemStateChangedEvent  ] - Item 'Iammeter_Current_A' changed from 239.1999969482422 V to 238.60000610351562 V
15:52:00.428 [INFO ] [openhab.event.ItemStateChangedEvent  ] - Item 'Iammeter_Voltage_A' changed from 1.4199999570846558 A to 1.5299999713897705 A

I could relink the channels to the mixed up order, but that is silly fix.

Is this something that 4.0.0 has caused, or has there been an update in the binding that has broken something?
