TRestRawMultiFEMINOSToSignalProcess: first two events are with the same id

I found that the first two events from TRestRawMultiFEMINOSToSignalProcess are with same id. Don't know if is the file/daq problem or the process's problem.

I download this file: https://github.com/rest-for-physics/rawlib/blob/master/pipeline/data/R01208_Ar2Iso_Background14h_14Vetos_IccubFEC-000.aqs

and type directly in restRoot:

TRestRawMultiFEMINOSToSignalProcess pc;  
pc.OpenInputFiles({"R01208_Ar2Iso_Background14h_14Vetos_IccubFEC-000.aqs"});
TRestRun r; 
pc.SetRunInfo(&r);
pc.InitProcess()

pc.ProcessEvent(NULL)->GetTimeStamp().GetNanoSec() //293870925
pc.ProcessEvent(NULL)->GetTimeStamp().GetNanoSec() //293870925
pc.ProcessEvent(NULL)->GetTimeStamp().GetNanoSec() //375673055
pc.ProcessEvent(NULL)->GetTimeStamp().GetNanoSec() //317906618

And see the timestamp of the first two events are same. We can also try event id, and see they are same. However, the signal data seems to be different, meaning that the events are not actually same.

TRestRawMultiFEMINOSToSignalProcess pc;  
pc.OpenInputFiles({"R01208_Ar2Iso_Background14h_14Vetos_IccubFEC-000.aqs"});
TRestRun r; 
pc.SetRunInfo(&r);
pc.InitProcess();

((TRestRawSignalEvent*)pc.ProcessEvent(NULL))->GetSignal(0)->GetData(0) //249
((TRestRawSignalEvent*)pc.ProcessEvent(NULL))->GetSignal(0)->GetData(0) //261
((TRestRawSignalEvent*)pc.ProcessEvent(NULL))->GetSignal(0)->GetData(0) //269
((TRestRawSignalEvent*)pc.ProcessEvent(NULL))->GetSignal(0)->GetData(0) //249

Reproduce the report through TRestRawMultiFEMINOSToSignalProcess using the referenced .aqs file and the shown ProcessEvent calls. Start by inspecting that process's event and ID handling, then compare it with the input data reader to determine whether the duplicate first ID comes from the file or conversion. Done means identifying the source and documenting or correcting the duplicate-ID behavior.
