I am running zen cart v1.5.1, I have instaled the short description add on that works fine for the product info page but when i turn it on on for the product list pages it just duplicates the text/picture in the postion that is nominated instead of adding the short description eg if i set it to 1 the picture is dupplicated or to 2 the product code is duplicted etc.

any ideas why this is happening and how it might be fixed.
