Multiple loraserver gateway update problem

i set up 1 app-server , 1 gateway-bridge,1 mqtt server and multiple loraserver(with different band) in one machine, loraservers work fine ,i create gateways on app-server UI and choose different server-profile (such as 433 ,470), but went i turn on my gateway , only one loraserver’s log show the gateway stats mqtt and update msg even it is not belong to this loraserver , occasionaly other loraserver can receive the UPDATE msg , so in my app-server UI ,the gateway stats info is not always the latest.

in my understanding , multiple loraservers will both receive all gateway msg , is it my mistakes in comprehension? or other problem ?
only one server show the log:

meanwhile other not or occasionaly does.
