LTM8071 output cannot be shutdown by setting “RUN” to 0V

Question

as shown by our schematics, LTM8071 output cannot be shutdown by set &ldquo;RUN&rdquo; to 0V. 
 We tested the voltage of RUN pin by multimeter, it showed 0V indeed. 
 We changed another chip of LTM8071, it was the same.

It is configured to a inverting converter according to the schematic. Please make sure RUN pin is pulled to low referring to GND of the module which is actually 'VOUT-'.
