None K40 decay error

I'm using the Geant4 version: 10.3.2 and I'm trying to get the daughters from the K40 decay. Everything is going good when the decay goes to Ca40 but I have the following error when the decay goes to Ar40:

-------- EEEE ------- G4Exception-START -------- EEEE -------
*** G4Exception : de0001
      issued by : G4AtomicTransitionManager::Shell()
No de-excitation for Z= 18  shellIndex= 0. AtomicShell not found - check if data are uploaded

*** Fatal Exception *** core dump *** -------- EEEE -------- G4Exception-END --------- EEEE -------

I checked and the data are there for Ar40, Ca40 and K40. I also checked the K40 decay table and seems good. In addition, I generated some K40 decays and I always obtained electronic capture on the Ar40 ground state. This is not normal, K40 decays at 10% into Ar40[1460,851] and 0.2% to Ar40[0].

Can you help me with this issue ? Best, Quentin Riffard
