RuntimeError: Duplicate Correction name

Hi, I am getting a correctionlib RuntimeError:

>>> import correctionlib
>>> correctionlib.__version__
'2.6.1'
>>> ceval = correctionlib.CorrectionSet.from_file('vll/scalefactors/EleMu/Muons/UL/2018/2018_trigger/Efficiencies_muon_generalTracks_Z_Run2018_UL_SingleMuonTriggers_schemaV2.json')
Traceback (most recent call last):

RuntimeError: Duplicate Correction name: NUM_IsoMu24_DEN_CutBasedIdMedium_and_PFIsoMedium

Here, the file used can be found from

https://gitlab.cern.ch/cms-muonPOG/muonefficiencies/-/blob/master/Run2/UL/2018/2018_trigger/Efficiencies_muon_generalTracks_Z_Run2018_UL_SingleMuonTriggers_schemaV2.json

The purpose of reading the json file was to read the trigger efficiency once the json file is read using this syntax (inputs, abseta and pt):

    sf_mu = ceval[key].evaluate(abs(mu_m.eta), mu_m.pt, "nominal")

So, I guess for now the name should be changed based on the input combinations with correctionlib 2.6.1. But there was no RuntimeError with the correctionlib 2.3.3. Thanks, Bockjoo
