Permalinks incorrect

Hello there 🙂

I got a new problem. i Just changed the permaliks on my blog, (before it was …/archives/number) now it’s …/day/month/year/name-of-post.
but i don’t know why some of my posts have link without the name of post at the end of the permalinks. No all posts, just some. I check in the page of the post in admin, and effectively there is not the name of the post at the end for these posts.
So my questions is :
– How i can correct that ? (not by checking one by one, more than 2500 posts at all)
– Is there plugin to check the permalink ? i already tried Broken links checker but like the links is not really broken (when you click on the post it send to a page with all the posts of the day of the post, but impossible to see the detail page of the posts) the plugin didn’t works in my case to find which posts have this problem.
Someone already had this problem ? help guys ! 🙂
