Selecting language at first login

I have installed erpnext.
Put the following files in place:
apps/shopping_cart/shopping_cart/translations/is.csv
apps/erpnext/erpnext/translations/is.csv
apps/frappe/frappe/translations/is.csv
and
Edited sites/languages.txt and /apps/frappe/frappe/data/languages.txt
Then when I connect with the browser on port 8000 I login in and the Wizard goes.
The first question the Wizard asks is to choose a language.
I can not find “Íslenska” (Icelandic)
But I have modified the two files mentioned above.
What do I need to do to be able to choose “Íslenska” (Icelandic)?

Did you build?

bench frappe --build

No I had not done that.
But I did this morning after receiving your suggestion.
But I still do not get the Icelandic (“Íslenska”) when the Wizard starts.
Are there some other changes that need to be done apart from what I mention in my earlier post?
Any help will be appreciated.

Is there anything I can do to add the Icelandic language so it will show up in the wizard or can someone help?

@bjarni this is a bug. Will fix it and get back to you.

Thanks for the update.

Hard coded here:

https://github.com/frappe/erpnext/blob/develop/erpnext/setup/page/setup_wizard/setup_wizard.js#L63

Would it not be better to load it from the TXT files that can be externally modified?
sites/languages.txt and /apps/frappe/frappe/data/languages.txt

Yeah - that was the bug @anand was referring to

Thanks for the explanation.
