OK then it is fairly obvious that somewhere in the circuit the black and/or white wires are not connecting as they should.
As suggested before, please check the single crimp where the black and white wires connect to the shunt.
THIS I WILL DO ASAP
Secondly, double check the connector block shown in your photo - maybe one of the wires is not actually connecting properly here, for example, you may have screwed into the insulation and not the wire. This is quite easy to do and looks like a good connection when in fact there is no connection.
THIS I ALREADY DID (TWICE).
Good hunting
