When checking the tag search list in the OPC Client tool, some tag lists are missing.

This is a list of tags registered in the cogent OPC server.

As you can see, if you compare the list of tags registered in the OPC Server (Cogent DataHub) and the list viewed in the OPC Client tool, you can see that they are different.

 

This is an issue where the one minute tag is missing.

Is there any reason?
