Blogger Duplicate content displays on my pages

I am using a free premium blogger template. I have tried various solutions I have read but the solutions do not work for me.
Problem: My content regardless of whether a post or a static page is displaying twice on my blog
The suggested solutions so far have been:
#Blog2{
display: none;
position: relative;
bottom: 99999;
}
#blog2 {
margin-top: -10px

<b:widget id='blog2' locked='false' title='Blog Posts' type=Blog'/>
or
#Blog2
{
visibility:hidden;
display:none…
