Translation can't use in conference.

Hi All,

I have a office mate who is chinese and cant understand english that much, so we use the translation in spark while chatting. The problem is another friend of ours wants to join in our discussion  so, we decided to create a group. Once everyone is already inside the group conference, we notice that the translation dialog box is missing. Can anyone have the same issue?

Openfire version: 3.10.0

Spark version: 2.7.0

Build:671

Smack Version: 3.3.1

JRE Version: 1.7.0_76

Thanks!

Siv
