Added tags spoil the alignment of column text

Hi Alex,
Thanks a lot for this amazing free theme, I really appreciate your effort. However, I am more or less a newby to all this web design stuff and I cannot figure out how to get rid of
tags that are added in my version when setting up columns. I just copied the short codes from the live demo page, but the output looks different on my page…
