Magento 2.0.7 "Urlkey for the store already exists" error while importing products

[Taral-Patoliya]

I am trying to import simple products, But it fails due to some validation error.
The error message i get is "Additional data: URL key for specified store already exists.".

I have checked the URL keys generated from the product names are all unique. but still i am having this annoying issue.

I am importing >10000 products.
