Mixed up content after using Include page macro

[Marian Vidra]

Hi guys, any idea why the content of the page gets randomly spread out all over the page after using of 'Include page macro'? The original content is fine but then it gets mixed up. 

The original content (above) is in the order but then it gets mixed up. Even in preview mode it looks alright (see the picture below).

But once it's Saved it gets randomly spread out all over the page.

Any idea on how to fix this and why is it happening?
