I think I've found a bug?
Claiming you have a bug is just annoying.
Just because it didn't do what you expected, it does not mean it is a bug.
If you have found a bug, you will have a unit test that shows there is a bug and be able to quote chapter and verse from the spec on the correct behaviour.
However, if you only think or believe or might have found a bug, you don't make any friends
If you have found a bug, it belongs on JIRA not the forums.
