Two problems with this com

Hello to everybody,

I'm using this great tool and i can say I'm impressed with it.

Unfortunately i have 2 issues and i want your help

1. Not all the article from the rss url are importing into my web (for example on the RSS link there are 8 new articles, on my website will import 5 or 6)

2. The second problem is the duplicate, most of the articles are importing twice. Ok some of them there is a reason, is the " (""). But some articles are totally the same, (title etc)

Can you help me?

The import language is Greek, maybe this is the reason?

Thanks
