Hidden poll can be viewed by all users

Hi everybody,
today i was installing the module for testing purpose an noticed that even if the creator of a node with the makemeeting field ticked the "hidden poll" option other people can see the exact option other users ticked.
All permissions are set correctly as far as i could set them for this module.

General information:
No other option was ticked. Limit was set to 0. I had 15 choices and two suggestions. All dates where set in the future. Not all suggestions where filled out (most of them had no text).

I hope i didn't overlook any issue or misunderstanding in the given function.
