Hi Alex, 

Thank you for your reply!  It was helpful and solved my initial problem.  However, I encountered another problem. Refer below.

1) I had installed the Russian language App to my UNA site. 

2) I then created a new Field called:  Ethnicity.    Your reply solved my problem.  I had to enter the Russian translation in order to add my new field. 

However, when I 'turned off' the Russian language App and proceeded to add some Data Items for my new Field:  Ethnicity,  the system wouldn't let me proceed with adding Data Items unless I also entered the Russian translation for each of my Data Items even though I had turned the 'Russian language' off.   Is this a bug?

Or, did I have to:

1) Turn off Russian language app

2) Delete the new field I created: Ethnicity

3) Recreate the field:  Ethnicity

4) the proceed to add Data Items for:  Ethnicity

- -

The attached image show that I had to still add the Russian translation even though I turned off Russian language App.

BTW, will is there a manual for UNA, other than the installation steps I found on github?

Once again, thank you for the support!

Simon
