Deleting Views from Orientation dialog box

I have several drawing where someone by mistake (I'm presuming) created about a dozen views in the orientation dialog box and I have not been ablt to eliminate these views from the dialog box. I have tried using the help forum and all I can find tells me to click on the view in the dialog box and press delete to get rid of it, however for some reason that is not working. Has anyone else encountered this problem and found a solution and way to eliminate all these extra views from the dialog box? My drawing has 5 views on it but as shown below there are 100 "Flat pattern" views.
