In this work we present the first results of a study of signal discrepancies between data and simulations with Golden Hybrid events measured with the SD-750 and HeCo. We follow the strategy of previous works but at a lower energies. We see a difference in the signal of the Water-Cherenkov detectors between the acquired and simulated events of about 25% (proton, QGSJet-II-04) that is attributable to the muon deficit in simulations. These results are compatible with those obtained with the Underground Muon Detector information in the same energy range.
