Templates and Themes

There are some CSS styles hard coded into mtEntryBody. No matter which template or theme I use it always gets the following written into my page;

 <div class="asset-body">

                                      <div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 10px; padding-right: 10px; padding-bottom: 10px; padding-left: 10px; height: 90%; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; background-image: initial; background-repeat: initial; background-attachment: initial; -webkit-background-clip: initial; -webkit-background-origin: initial; background-color: rgb(255, 255, 255); color: rgb(51, 51, 51); font: normal normal normal 13px/normal arial, helvetica, hirakakupro-w3, osaka, 'ms pgothic', sans-serif; background-position: initial initial; "> 

These cannot be over written by the style sheets.

As mtEntryBody is not a template or a widget it has been impossible to track down where this tag is written into the templating system in order to remove it.

It's really destructive to most themes and I would be grateful for help or advice in how to remove it.
