[Plugin: TXTAsPost] can not remove posts made by this tool

i used this tool as described in the readme except all of the posts had zero text and now i would like to remove the bad posts but wordpress will not let me delete the posts… it says it moves them to the trash but they infact stay put. is there anyway to go in and manually remove these posts?
