The verdict is not great. Firstly I confirmed that the switch was only being activated by one bucket, and it was always the same one. I found that by holding the PCB containing the switch away from the magnet corrected the issue. I put a blob of hot glue on the PCB to make a spacer. Now the switch 'ticks' on both bucket tips.
However now I discovered the other issue. One bucket requires considerably more water to tip, effectively requiring just over 2mm at least to make 3 tips to register the 0.9 to 1mm.
I thought perhaps some hot glue to the offending bucket would balance this out. It has taken a lot of messing about to bring it close on the bench. Back in the field it just was not going to cut it. I checked with my spirit level again, and the sensor is definitely level sitting on the bracket.
I think I am just unlucky with this particular unit, and will have to cut my losses.
