Gamma pics in beta spectrum?

Hello everyone,
I am trying to simulate beta spectrum using Geant4/examples/extended/radioactivedecay/rdecay01. In fact the problem is that when asking for the beta spectrum, it gives me a beta spectrum but with gamma pics. I am trying to understand why the program includes gamma and RX deexitation pics in the veta spectrum, if there is any one that can help please ?

It is possible to visualize in this figure, which is the beta spectrum of Lu177, the RX and gamma pics in the beta spectrum. It should be noted that the rx deexitation pics have been successfully removed by deleeting the deex process in the physics list, however the gamma pics are still there.
Thanks for any help.

In rdecay01, electrons and gamma spectrum are separated.
You see the electrons of internal conversion associated to the deexcitation of Hf177 excited states.
With fullChain = false, this deexcitation will not happen.
