Uncaught Error: E_MISSING_BUNDLE: {"locale":"en-US"}

Hi,

I get the following error "Uncaught Error: E_MISSING_BUNDLE: {"locale":"en-US"}" when I change from de-DE to en-US. de-DE works fine.

The error is in cldr.js file and the bundle is null
validate( "E_MISSING_BUNDLE", this.attributes.bundle !== null, {
locale: this.locale

Thanks
