The plugin is publishing several times the same posts.

Hello, In setting there is an option that says... "Update Post If It Is Already Posted > Select if you want to update the post when it is found as it is already posted (by title). If you uncheck this value, if duplicate post found, no action will be taken." I have this option unchecked but crawlomatic is posting several times the same post. Any idea about it and to solve this problem? Thanks
