akregator

I have a small question about Akregator.

All threads from this website seems to double at the end of day. None of the other feeds are doing this, only this one. I have deleted the folder and re-make it. I have started with an empty folder in the morning. Everything will run as it should all day long, then all of a sudden everything will double at the end of the day.

Does anyone understand what is going on.
