AI agent not creating helpdesk requests with categories for employees from different Business Unit

Summary:

Hello All,

We are implementing HR Helpdesk (26B), we enabled the AI agent for helpdesk and loaded the categories to RAG so that the AI Assistant can raise the tickets under appropriate category.
We have multiple BUs and Help Desk will be implemented for each. For now we loaded the categories for one BU. When an employee from this BU is using the AI assistant to log a helpdesk request, it is logging a ticket with proper category. But when the same is tried for another employee from a different BU, it is logging a ticket but is not assigning any category.
