Listing descriptions are messed up?

I have had a few people message me today, to tell me that my descriptions don't match my listing headings.
I went and checked a few of them and they are the descriptions are from different listings. It's completely messed up.
Can someone tell me why this happened. The listings were fine yesterday?

Do you know which listings are affected? (I looked at several but they all seemed to match up fine). 

 

I haven't noticed anything on my listings (not that it isn't possible, just that I haven't seen or heard about a technical issue that would cause the problem).

 

Can't help with the description change.

I've just had a look at my listings (didn't go into the description though), just a few of my initial photos have switched to one in the gallery & I make sure of which photos are in which place.

Very strange, I've fixed the ones I have found.

It was about three or four of my listings where the descriptions had somehow swapped over. I revised the listings fairly promptly, just curious as to how it could have happened? 

I wonder if that has anything to do with my overseas buyers today and yesterday- who are blocked, I haven't sold OS for a long long time.
