So one tree will give only one reward. Two trees and the box will give you two and so on. Then the timer resets for another week, and the icons for all trees disappear.
2. That part actually is a glitch. It is that same annoying 'lag'/hiccup/freeze nonsense that messes up everything else (buffing, posting a trade, completing a quest...) so you you don't get to see what you got. Though you should have got something. (The action works fine on the server, just not on your UI, and when the game resyncs whatever you got is already in star and you will never get to know what it was unless you have a good memory of what you had or something is now there completely out of place)
