Custom agent is not loaded correctly even when it's showing in the bottom status line

### Describe the bug

Copilot showing my custom agent is current agent, but it's not using the skills it has. When asked why dont you use it, it says ' I am not xxxx agent, am copilot cli agent.'
There's a detachment between what's showing as the agent and what's actully loaded as the current agent.
