TRB145 Modbus Client Read issue

Hi, I have an issue with reading multiple Modbus meters with the TRB145.
I have 4 meters connected to the RS485 Port and have setup 4 Serial Clients.
They are set to read them meters every 900 seconds.
I am only reading 1 register from each meter.
I have also setup a data to Server MQTT push to send the data to a remote broker.

If I go into each of the Modbus Clients and push the Test Button, it reads the value fine.
But when left to read them automatically it only reads the first 2 out of the 4 meters and fails to read the other 2.
The odd time it reads 3 but has not managed to read all 4 in 24hours of testing.
If I swap the meter addresses round in the clients i.e. 1,2,3,4 to 4,3,2,1 then I get the other 2 meters reading and not the initial ones, proving it’s not a meter or wiring issue.

Any help on this issue would be much appreciated!
Thanks
