Translated strings not showing

Hi,

I have the following problem. Some strings that are translated (I have also checked in the database) are not showing the translated version, but are displayed in the main language version. The interesting part of the issue is that these are blog posts titles, when the post is viewed the title is translated, but when you check the homepage where are displayed latest post the title is not showing the translated version. Hopefully I’ve explained the problem so that you can understand it.
