None Time of Products from Nuclear Muon Capture

I'm having problems with the timing of products from nuclear muon capture in Geant4.10.00.p02.

My simulation fires muons at an aluminum target and there is a sensitive detector volume separately that records anything emitted from it. However, the global arrival time of these protons is much too short when compared to the muonic atom lifetime (864ns). I've attached a plot to show the actual arrival times.

I'm using physics list QGSP_BERT.hh, which uses G4StoppingPhysics which then uses G4MuonMinusCapture.

From a little bit of debugging myself it seems that the random time generated by G4MuonMinusCapture is not used for the nuclear cascade but is used for the decay.

Does anyone know how this should be solved?
