Where is the update geocache button on a small screen phone?

I am terporarily forced to use an old phone of mine, small-screen HTC Desire, Android 2.3, and while I wanted to use it for geocaching, I noticed I can't see the normal geocache-related menu under the "puzzle button". The menu where the "update geocache" is.

When I press the puzzle button, I can't see the features I am used to. See the picture.

1) Where did the menu go? Is it because of the small screen or is it a bug?

2) How can I update a geocache? I really need to do so.
