[BUG/ISSUE] HEMCO WARNING: Data is treated as unitless

Description of the problem

I manually downloaded the Geos-Chem restart files along with the HEMCO restart files from "http://ftp.as.harvard.edu/gcgrid/geos-chem/10yr_benchmarks/13.0.0/GCClassic/restarts/". First of all, I was wondering if it is reasonable to just copy those restart files to my rundirs? I tried in this way and the Geos-Chem worked well anyway. However, there were so many warnings from the HEMCO.log, and I don't know why this happened.
GEOS-Chem version

GEOS-Chem version 13.1.0.
