CREATING A LOCALIZATION READY GAME IN UE4: Part 1 - Text

I created a basic main menu using the widget blueprint and bound the texts of the button. The binding functions use text variables.
The project is also setup for localization. But when I run the commandlets I can’t find the texts of the buttons in the generated data.

So how do I do this?

Edit: I tried the experimental localization dashboard. It finds all texts and I found out that I don’t have to bind the button texts with a text variable. But I still would like to know how I achieve this with the currently supported method.
