Can't translate title

I can't translate the title in 2.5.1.
Have already done everything with search and replace.
Unfortunately it says here in the "New Products"...

Admin -> Translations -> Search for New Products
The key is title_new_products

Thank you very much for the tip! That's how it works :-)
