Problems with alias joomla?

Question

CMS

Good afternoon! A ready-made site with a large number of goods fell into my hands. And some items do not open correctly. The non-working view link is as follows: http://website/content-view-4191
However! It has a link like: http://site/content/view/4191/ , which will give everything in the absolutely right way.
I tested everything, when adding a new product - there is no error. Those. Apparently there was an incorrect transfer of goods? Maybe someone knows where to dig or faced this? I looked at the pseudonyms in the product pages, they are of the form "content-view-4191", replacing them with "/content/view/4191/" did not give anything... Version 2.5
