Error on bulk import of products.csv file

[eliteitsolutions.ie]

I'm having an issue when uploading a bulk import of a products file. It's allowing 102 products to be uploaded to one of my categories but not allowing the other 100+ products to the other categories.

However 2 products from two other categories are being allowed to be uploaded.

This is the error I'm receiving:
 

[PrestaShopException]

Is there anyone that can help me on this please? It would be a great help rather than adding all the products individually. Thanks
