MP1584 switching psu board problem.

I started to use some from a batch of 10 I bought a few weeks ago and found that the output was stuck at 0.8v, the MP1584 reference voltage.
On closer inspection, the pots have been put on the wrong way round and are effectively short circuit. The single pin end of the pot, with the small endstop tab, should go towards the nearby board positive output.
