I noticed that on a manual landing when I disconnect the autothrottle with the button on the side of the throttle, the autothrottle indeed disconnects. But when I land the aircraft, it connects itself again and the aircraft increases speed again.

The only way to prevent increasing speed after landing, is to switch of the AT ARM on the MCP. I assume this is a bug?

Can somebody tell me you have the same problem?

Kind regards,
Kees
