There is a overshooting for  W-186 when using G4GammaNuclearXS (G4GNXS)

I am benchmarking the Geant4 cross-section of the photonuclear reaction on a deformed target.I used Geant4 built-in cross-section models: G4PhotoNuclearCrossSection (G4PNXS) and G4GammaNuclearXS (G4GNXS).
In my benchmark, I found out that G4GNXS well-regenerated experimental data for Eu153 and Gd160.
But for W186 or Ho165, there is an overshooting of the cross-section with G4GammaNuclearXS as can be seen in the attached picture.
These may refer that for W, and Ho there is a problem, which requires investigation. This problem may mean that data inside DB itself requires correction. The exact reason, why extracted data has this problem requires investigation to provide a solid solution.
