Unable to add column to existing table error The style "tabledetailslabelcell" used by Cell

<p>Trying to troubleshoot this so I don't have to rewrite the entire report, I get the error above when right clicking on the colum and trying to add column to either left or right.</p>
<p>Appears to be an embedded table, didn't write this report.</p>
<p>Error when attempting is 'The style "table details label cell" used by Cell is not found'</p>
