I would check the Metadata (IPTC) Info dialog in Photo Mechanic after Ingest to make sure the Metadata Template wrote the City, State and Country info. If the info is present, then I would check Photoshop's File Info to make sure the info is still present after sending the file from PM. If it is, then how are you saving this file from Photoshop? Does this problem happen with all files saved from Photoshop or just some?
