Trying to cleanup message Umap failed to load a file

Getting several messages of

LogLinker: While loading ‘C:XX.umap’ failed to load ‘/Game/MeasurementSystem/Meshes/SM_1M_Cylinder’: Can’t find file.

It is legit as the files are missing. At some point I got rid of them.

My question is, how to I get the map to stop referencing them?

Wow…validating contents of the Content directory…that is going to be a bit…
