**Current behavior**

$ ./bin/translate hello -f en -t zh
你好- F EN T zh

**Expected behavior**

$ ./bin/translate hello -f en -t zh
你好

**More default**

**Please tell us about your environment:**
Linux

Reproduce the issue with ./bin/translate hello -f en -t zh and start by tracing the bin/translate entry point to where translated output is assembled. Done means the command prints only 你好, without the '- F EN T zh' suffix, while preserving expected translation behavior.
