Dashboard: Stories appear in random folders

First of all, thanks for your hard work, i´ve been trying out NewsBlur for a few days now and i like it a lot so far! There´s one problem though.

Right now, i have my feeds organized within three folders, which i´ve put on my dashboard. Now, when the dashboard auto-updates, it sometimes produces weird results. It seems like many stories are put randomly in a wrong folder instead of the one they are original placed in. This doesn´t happen all the time, but after a while of auto-updating, it´s likely to happen. A refresh of the webpage gets everything in order again, but after a while, the misplacement will start again.

Is this a known problem? Any ideas how to fix it?

Thanks in advance!
