SEO URLs - wrong product's name

[alastrina]

Hi. I just noticed a problem with the SEO URLs. For example, I have a product with ID 10 named "Glass". Address should look like: /glass-p-10.html, but it looks like this: /knife-p-10.html. The name in the URL is from a different product but the ID is correct (I know that I can write sth like: /lorem-ipsum-dolor-p-10.html and I will get to the page with product "Glass" but.. there's something wrong and I should to fix it). This happens only with certain products. Sometimes the name in the URL is form an old product name. I noticed that when I restore an old copy of the database, the problem is gone. Something has happened in the database. Unfortunately, I do not know what. Generally I use the sales system, which synchronizes its database with a store's database. I removed the categories and products from the store's database and synchronize everything but it's still wrong. I didnt edit any of files, so it must be something with database..

 

Do you have any ideas where can be a mistake?
