Single Product Page – Content Description Area 'Weirdness' ???

Hi,
I have a weird thing that happens on the single product page..

Firstly, on the product/edit page there are two content description areas. One at the top and one below the Product DATA labelled ‘Product Short Description’. (top one doesn’t have a label)
The top content description area is displayed in the product page description area at the bottom
The bottom content description area is displayed at the top, just below the Product Title.

I have no idea why this happens buts its weird and I’ve got used to it.

Hope this is making some sense..

Secondly, something else happens.. and now all the time.

The bottom content description area has the following (in text view):

[av_font_icon icon='ue835' font='entypo-fontello' style='' caption='' link='' linktarget='' size='25px' position='left' color='#f7a288' custom_class=''][/av_font_icon]return to home

When the edit page has been updated/refreshed – it changes and displays the same code below. If I update whilst its showing all these &, # etc… it messes it up.
For example – the icon defined below in the shortcode disappears. And a “ appears right-side of the content.

[av_font_icon icon='ue835' font='entypo-fontello' style='' caption='' link='' linktarget='' size='25px' position='left' color='#f7a288' custom_class=''][/av_font_icon]return to home

The workaround is – on the edit page I toggle the content description area box view from Visual to Text. The result is it converts it back to what it should be.
