After updating our 6k+ products in Magento 1.7 using CSV import with Magmi the url_keys for all product get 4-digit numbers as suffix.
e.g. before it was www.domain.com/productname.html after update it's www.dmain.com/productname-5363.html
This happens although the url_key in CSV is set as "productname"
Only way to fix it is to clear all urls from database and reindex - but after next import it's happening again.
Has anyone an idea how to prevent this on import?
