Local Farm Agent Shown as "Not Used"

 
I think, since after I have imported Dukacopy tick and bar to severals custom symbols, my local network farm agents became "not used".

Is there a way to use the remote agents for non customised symbols?

I have tried to use local symbols, ochl in local terminal and yet connect to agents are still shown as "not use".




and there is no way I can enable them:
