[Solved]Prestashop Database Question

[LLT]

I successfully imported all of my products and categories from Oscommerce 2.2-Ms2 to Prestashop 1.4.4.1 but when I look at the ps_product_lang table in the database, I can see each product duplicated 4 times with different lang id's and I only use english on my shop. I don't have duplicated products on my storefront so is it ok to delete these from the database or is this something Prestashop needs?

 

I know I can leave it as is since it isn't doing any harm but I want to keep my database as clean as possible to keep query times as fast as possible.

 

UPDATE: Even though I was only using english on my shop, I never deleted the other languages and that is why it listed my products 4 times in the ps_products_lang database. Once I deleted the other languages, they were removed.
