Hi all,

I'm new with rapidminer and tried to read rss feeds and put it in some files like this tutorial on vimeo (https://vimeo.com/62963128). Almost everything works, but I have one problem. The process generates every file twice. File 1 and 21 are the same file, file 2 and 22 are the same file, and so on. Does anybody knows what I'm doing wrong?
