wrong text in split layout

Hi. I have a recurring problem with a newsfeed in split layout. The list
of stories in the feed seems all right but and most of the time I can
select a story to read and the right content will show up in the text view. However, some stories misbehave and content from another story will be displayed. When a story misbehaves it always does so.

I’m not sure if it’s a problem with the feed or with newsblur. However, it’s starting to get on my nerves as my main news feed is affected and I’m reading it every day. And it’s one of the biggest IT news providers in Germany. It would be great if someone could help.

Here’s an example:

Feed URL: http://www.heise.de/newsticker/heise-atom.xml
Broken Story:

   Seagate trennt sich vom Online-Backup-Geschäft
   20.12.2015 12:00 Uhr

Here’s a screenshot:

This story is also displayed incorrectly on my on my mobile (newsblur Android App on Samsung SGS3).

Thanks for any help.
