Need help ASAP on my reefer

This is when I had the fresh protect on
The supply air for the fresh protect is at 30degrees

When I turned of the fresh protect the unit went down to as low as 32.7 but it eventually settled exactly at 34 degrees, the supply air temp was at 24 degrees at this time, but make sure u don't have the air coming of the chute blowing directly at uncovered produce cases or it'll frost the top cases.
