Hi,
If you check the link I gave, it says:
You must implement a simple output override to accomplish the login module label in my attached screenshot. The constants to override are:
COMUSERSLOGINUSERNAMELABEL
COMUSERSFIELDRESETCONFIRMUSERNAMELABEL
MODLOGINVALUE_USERNAME
So you need to add these translation overrides. You can do it via the Joomla translations override interface:

And I'm sorry but I don't know what protection you have installed. I would recommend you post about your issue on forum.joomla.org
There, there are people who know more about this kind of things than us, since we work mainly with HikaShop and the other extensions we released.
