Have you tried setting the info mode through the menu, or via the remote control.
The way it works is that two info modes are persisted per channel, one last full screen one selected, and the last non-full screen one selected. Holding the bottom button will toggle these two modes.
Try selecting your favourite full screen info mode through the menu, then selecting your favourite non-fullscreen info mode through the menu. Once you have done this, providing you don't cycle through again with the remote (this issue may be addresed in a future release) you should find that holding the bottom button toggles correctly.
Let me know if it doesn't
