Product Import Not Updating Data

I’ve been trying to use product import/export to update SEO names for all our products.

I can export okay and then import in again without generating errors. It even reports back that products have been updated (and no new products added for example), but when I check the SEO names individual under any of the products they haven’t changed.

I’m only exporting/importing the bare minimum data (store,product code,language) plus “SEO name”.

Any thoughts?

I’m using 4.2.1.

I found a fix.

Seems you can't upload SEO for multiple stores at once.

Plus generating error in cscart_seo_names table where I had to change 'path' for NULL is 'yes'.
