Units Synchronization Alert: I am receiving this error when using City of San Diego Seed file (non metric)

I am receiving this error when using City of San Diego Seed file (non metric) found here:  https://www.sandiego.gov/publicworks/edocref/drawings

My working units are set to US Survey Feet and my units definition is defined and operating properly. The error pops up whenever I activate geopak. I see this has been discussed before but the previous discussions do not have information that has solved my problem.
