The club has (2) 6-14077 Readouts mounted on the ZW-C transformers. After checking with a analog meter in series with the outputs of the transformer the reading shows about half the value of amperage to the track.
Has anyone found a way to change the value on the display to correct this error?

Might need to replace the 9V internal rechargeable battery, especially if it has never been replaced before.
The meter should be a 6-14002 if it is on a ZW-C. Are you testing with a load? How many channels on the ZW-C are powered? The amperage on the ZW-C meter is read across all the outputs, since they are all interconnected. Dale Manquen documented this on the forum when he was around. This can cause crazy readings depending on how the ZW is connected to the track and what loads are on each of the channels.

The meters on the ZW-C's are 6-14002's. I have asked before about telling the two models apart, 6-14022/6-14077.
The ZW-C's are connected to the tracks thru the A and D handles on each. As a consist travels from one track to another, the meters follow the amperage readings follow, i.e. 2.6 on one to 2.6 on the other. There are four circuits for the tracks, inside, middle, outside plus the yard for a total of four. The problem remains, a analog meter in line with the output from the transformer indicates a 5.2 amps. Should be a component change to shunt the meter circuit to indicate the correct amperage.

That’s correct and that’s your issue. You cannot rely on the ZW meter amperage in your case.
