[Bug] API-downloaded entries for binary systems containing 'Yb' missing the element in composition

[willwerj]

I have been downloading a large amount of GGA/GGA+U entries for binary systems, and something I have noticed is that all systems containing 'Yb' as one of the two elements are missing the element in the entry composition.

I am using the the API version mp-api==0.39.5

Here is an example from the code that I am using:

entries = MPR.get_entries_in_chemsys(['Yb', 'Fe'], additional_criteria={'thermo_types' [ThermoType.GGA_GGA_U]})

print(entries)

Output:

Unfortunately we have had to deprecate all Yb compounds as of the latest data release: https://docs.materialsproject.org/changes/database-versions

We are currently re-running the calculations and will be updating them soon.
