JQuery Mobile adding ui-corner-bottom to first list item

I have been trying out JQuery Mobile with some success. The problem i'm now ha开发者_如何学JAVAving is the first line of my list has added 'ui-corner-bottom' to the class, creating first list item to have corners on the bottom. Any help or ideas on this more than welcome.
