For Kindle, different ASIN means different edition, just like for paper editions different ISBN means different edition. I truly hope you were not deleting Kindle editions with different ASINs just because they have the same number of pages.

OK. But I suspected it was duplicate even they have different ISBN. Because I have seen many Bengali books duplicately imported from amazon with various duplicate data. That's why I requested to merge these.
