Slugs not changing

Hi there, i have a woocommerce shop and although i have changed the category slugs, in the database i see no changes… at the site’s front, everything is ok, but when i try to view a category from the wp backoffice (the VIEW button) it sends me to the old category slug. At the db i also see that it has the old slug… what am i doing wrong here??

thanks in advance
Kostas
