Machine Translation broken for certain source languages

We are working on a project translating from zh_CN to en_US. However while we were configuring the Machine Translation we found it was really weird, that even though we configured everything right it grayed out the autotranslate button, until we created another project and set zh(no country code) as source language to test it out, everything works. As the existing translate project is already in progress and we dont want to start it over again, it would be really appreciated to fix this problem.

Hi @nicholascw,

I checked this out and I could reproduce the issue for Google MT service. I have forwarded this to our development team for further investigation.

Thank you for taking the time to report this.
