System Message Library returns extra 2 empty messages.

So I'm just looking at the system message library. When you render the messages, there are 2 extra message items which are empty. So for example when you render the messages, you get:

<p></p>
<p>Some message here</p>
<p></p>

instead of just:

<p>Some message here</p>

So it seems there are 2 extra empty messages in the array which I can't seem to find how they got there.
