Not to be confused with a "Core Material" - I know what that is.

We are using 2023x.  When we view Raw Material Objects in our Change Actions "Realized Changes" List, configured as "Grid View",  we are seeing these items listed as "Core Applied Materials".  They have long names that resemble a GUID and are identified with the same icon that is used for Core Materials.

When we try to search for the items using the GUID like name,  No object is found by the search engine.

Any thoughts?
