A vendor is attached to a product, so if you're uploading products and the vendor is actually changing afterwards this would suggest you have an app (or person) making secondary changes.
If you've just uploading products with a wrong vendor in error it's not too late to go back and bulk edit the vendor or just manually change each.
It's not 100% clear to me the issue you're facing so i've thrown those two comments out above to get things started.
I jump on these forums to help and share some insights. Not looking to be hired, and not looking for work.
Don't hand out staff invites or give admin password to forum members unless absolutely needed. In most cases the help you need can be handled without that.
