Price table using other languages

Hello Skywarriors,

I’m currently setting up he price tables in oblivion.
The website is in german.

The problem is that I have to enter either “Yes” or “No” to display the checkmark or the X.
However, when I save the template it shows correctly in the frontend, but as soon as I go back to the admin panel “Yes” and “No” are automatically translated and in order to display the checkmarks I need to reenter “Yes” or “No” again.

Is there a spot where I can enter the allowed Values so the checkmarks also appear for “Ja” and “Nein”?

Or is changing the language to english the only way to fix this?

Thx,
Leon
