AI Agent Tools Node Creating Duplicate Events Instead of Unique Ones?

I switched from MCP to the new AI Agent Tools node in my self-hosted n8n instance. I asked it to create 6 calendar events in one message. It responded fast, but when I checked my calendar, it had created the same event 6 times instead of 6 unique ones.

The same prompt works perfectly with the MCP node, creating all events correctly.

Has anyone else run into this? Is this a bug with how AI Agent Tools handles multi-event prompts?
