Maybe the shift is real due to chemical shift of the sample relative to reference material?

I have attached an (D)Athena project with containing two groups, imported as a primary data set and a reference. The groups were therefore imported on the same energy grid. However, when plotted, the energy values of the data points for the two groups are clearly shifted with respect to each other. Can someone please explain the origin of this shift?

Thank you,
