If you set fallback culture to en I imagine that things should start working. This should be considered a bug however.
I have Finnish as the fallback language. I changed that to English as you suggested and it fixed the problem. Thank you!
I'll do a bug report of this anyways so hopefully it'll be fixed for the next release.

When accessing the Edit mode only part of the left side page tree panel is rendered, nothing else. In the console I get the following error:
Any idea what might be causing this?
