The topic starter telling you to replace things, but you have add it under or above it.
So that`s the reason why you are seeing it twice.
What you have to do, is revert your template (postbit or postbit legacy) the one you have used and give it a another try.
But. before you revert your template which one you have used. Make a copy and past it in a new document and save it.
And a another thing, never place your xml template in a topic. Because everyone can use your work.
