Usually this is when it is realized a part/colour combination is incorrect. I'm guessing (and correct me if I'm wrong) that you're looking at the entry for Blue (which doesn't have an image and seems to not exist in this colour despite stores selling it). It looks like it should be either Dark Blue or Pearl Blue and it's likely those stores have Pearl Blue but have either not identified it correctly or Pearl Blue has recently been added to the colour database and they need to switch it across.
Once all stores have done this I believe the entry will then be deleted to prevent further errors.
