I have a saved expanded view that sometimes loses some displayed thoughts. Re-invoking it usually resolves it. 
However, even stranger, sometimes thoughts are duplicated. In the image, the ImportCSAT thought is highlighted with mouseover, to show that it's the same thought that's appearing twice. 
It's always the same one. I haven't noticed any issues with the actual thought in any other view, so I'm guessing it's a display issue and not thought corruption.
