Re narrative to emails in my left hand pane

Hello, I have today started seeing part narrative on my left hand pane under the person who has sent me the email. However I only want to see the details of my email in my right hand pane as the left hand pane is supposed to be only my summary. Can anybody let me know how to switch the format back to normal? I have tried everything. Thanks Thelma

Gary you are an absolute star!!! How did it get like this in the first place but I have now disabled and everything is back to normal. High Five!!!
