Hunters Are Not Attacking Thieves and Buffers Are not Buffing

Hi everyone,
Here’s the problem I am facing in a nutshell; i click Players tab and choose which player to trace, my hunter traces my trader but not attacking the thieves.
Also I am forming a party of 8 including 5 traders and 3 hunters I want my buffers to buff my hunters and continue to trace my selected trader, how can I do that?
Thanks in advance for your help.

Same on me
