Hi Tia,
I got confused in the topic you opened yesterday whether you are referring to WDA or WDJ, but after revisiting this older thread I see we are talking about WDA.
In that case let me confirm, as it was already stated, that you can't provide translation via WDA customizing/personalization.
There's even a note about it - check 1417637.
It clearly says:
Don´t "translate" them into other languages by changing these values simply in different customizing languages
Check this SAP note for further details
