Possible Piano roll bug - Or user error?

[zerozombie]

Hey all, thanks for looking over my question.

For some reason I have noticed that, at times in the piano roll, a note will duplicate and stack.
This causes problemsmaking the note seem to 'hit harder' and louder, unless I go in a delete all the duplicate notes.

First, is this even a bug? Is this something I can turn off?
Second, it there a way to find all these notes and remove them quickly instead of checking each one and deleting the duplicates?

Here is a quick screencast hosted on Mediafire.

As you can see in the video, I just simply move the duplicate notes and delete them.
But Im having this issue with several projects.

Please help.
Thanks
