Hi I also get the ones you are referring to. A few months back I got them like on 60 listings in 3 days.
Interesting part is the picture so far is always correct when I go and look at it. So it is like a false warning, it does not show up on auctiva as warning either, so if you miss email you have not notification that there may be a problem or there may not be a problem.
I contacted ebay and of course, they say to contact my third party service. SInce they show in listing I have not contacted auctiva, but is irritating to have to go in and check them. (just to make doubly sure)
Thanks
