We report the observation of sharp suppression of superconductivity-inducedzero-bias conductance peaks at low magnetic fields in InSb nanowire Josephsonquantum dot devices. With multiple gates, the quantum dot devices can be tunedto the Kondo-superconductivity interplaying regime, in which Kondo-enhancedsuperconductivity manifests as a zero-bias conductance peak. In weak magneticfields, the zero-bias conductance peak is found to exhibit an unusual negativemagnetoresistance when the Kondo temperature is comparable to thesuperconductor gap. The observation could not be explained by magnetic fieldinduced '0-$\pi$' phase transition, topological phase transition, or otherknown mechanisms, but may arise from correlation induced interference whenCooper pairs cotunnel through the quantum dots.
