0 imported reviews

I am trying to import reviews but it’s just not working.
This is the first few lines of the csv file :
“product_handle,state,rating,title,author,email,location,body,imageUrl,reply,created_at,replied_at
vegeta-dragon-ball-anime-tshirt,published,5,”Prince Saiyan [ Majin Vegeta’s Smile Face Mask]”,sunil,shopify@shopify.com,,”Unique design..grt deal”,,,”2016-09-05 19:48:38″,
survey-corps-attack-on-titan-keychain,published,4,”Survey Corps Logo Keychain”,”Anirban “,shopify@shopify.com,,”Nice collectible. Not delivered in UP.”,,,”2016-09-13 11:42:07″,
kaneki-1000-7-tokyo-ghoul-tshirt,published,5,”What’s 1000-7? [ Ghoul Face Mask]”,james,shopify@shopify.com,,”its amazing . just like in the picture.was not dissapointed”,,,”2016-10-16 03:28:05″,
”

I have mapped all the required columns plus 1 image column, but it just loads the entire file and says “0 reviews imported”
