Book Listing Error

I was trying to list my books on amazon with the ISBN I got from isbn.gov.in (Raja Ram Mohan Roy) but as soon as I'm selecting my binding as Perfect paperback, it is showcasing error 8541: The value Perfect Paperback specified cannot be used as it conflicts with the value apparel for ASIN 8196940297 in the Amazon catalogue. If this is ASIN 8196940297, then update the value to match with the ASIN data. If this is a different product, then update identifying information (UPC/EAN/Part Number, etc.)

I've tried contacting the seller support team but they are telling me that they are unable to verify my ISBN. How shall I proceed Further
