I recently moved to Mathematica 15.0. In the earlier versions, I had access to

Entity["AnatomicalStructure", "RightHumerus"]

and numerous other specific anatomical structure don''t work. For example I can't run

AnatomyPlot3D[Entity["AnatomicalStructure",  "RightHumerus"]]

which worked for me in the previous version of Mathematica.

Structures that are in the help files do work, so I can work with Entity["AnatomicalStructure", "Skull"] and do things like AnatomyPlot3D[Entity["AnatomicalStructure", "SetOfBones"]].

I would appreciate if someone could run AnatomyPlot3D[Entity["AnatomicalStructure", "RightHumerus"]] on either 14.x or 15.0 and see if they have the same problem. I could not get online support to do anything for me.
