MBox N3 won't switch to English

ronhip

I just purchased an MBox N3. In the settings when I switch to English it stays in German and won't switch. I've tried to switch to other languages (Spanish, for example, which works) and then switched back to English, but it switches to German.  Some of the labels switch to English, but not all. It's a mixed bag. Any clues?
Software version 3.10.189.0313
MBox N3 E_223B
