English is my first language, but frankly I think you do have a problem with your pictures.
You are using closeups of the brochures and cutting out the titles and other indications that they are patterns and not actual made items.
Try to look at the Frilly Fashions ad and the following Barbie Flora of Miami. The first is fairly easy to spot as a booklet, the second , not really.
And as you say, if you add in language problems....
Could you scan your brochures to show the interiors with the written patterns (not all obviously, but enough to show what they are0?
Could you retake the pictures from a greater distance to show that they are brochures/patterns?
Start with the 26 cancelled sales, while they are in your Unsold list, you could pull them from stock and redo the pictures.
BTW, I realize this is a lot of work. I started relisting my books from eBaydotcom to eBayCA when they stupid media cap came in. It's been about 18 months and I am still finding books on the wrong site.
