Menu looks different on node view, than on other pages.

I have two languages (default german, the other is english), two german nodes node/1 and node/2, and an english translation for node/2 at node/3.

When browsing normal pages in english (like in the admin area), the menu shows
en/node/1
en/node-3-alias

"Force content selection mode to off" not checked:

When browsing en/node/1:
en/node/1
en/node/2

When browsing en/node/2:
en/node/1
en/node/2

When browsing en/node-3-alias:
en/node-3-alias

When browsing admin/build:
en/node/1
en/node-3-alias

"Force content selection mode to off" checked:

When browsing en/node/1:
en/node/1
en/node-3-alias
en/node/2

When browsing en/node/2:
en/node/1
en/node-3-alias
en/node/2

When browsing en/node-3-alias:
en/node/1
en/node-3-alias
en/node/2

When browsing admin/build:
en/node/1
en/node-3-alias

None of this is what I want. I would like it all to behave like on admin/build !! Otherwise, what's the point of this module?
