I downloaded the langkit and just edited the blueprint default.yml, it looks like this:
title: Page
fields:
title:
label: Title
type: text
text:
label: Text
type: textarea
Image:
label: Image
type: image
Please look at the video. I add am image and switch languages a few times. At some point, it is messed up and one of the language files is overwritten. This is what drives our editors crazy.
A similar thing is already filed, but I wanted to mention that it is the image picker in the panel that causes the problem.

Does that help? β Martin
