The TAG update how does it work?

Hi,

The TAG update how does it work?

I set this on the server: OCS_OPT_ACCEPT_TAG_UPDATE_FROM_CLIENT = 1

I have a workstation. I install an agent with TAG: OLD. The 'OLD' TAG is displayed on the web interface.

I am uninstalling the existing agent. I am installing another one. Its  TAG: NEW. The TAG is not updated on the web interface. I tried to force. I deleted the machine from the database. Unfortunately, the old tag reappeared.

Server: 2.6, Agent: 2.6.0.1

Please, help me!
