Localizated Audio

Hi im wondering if someone can tell me how can i localizate audio voices to have Spanish and English voices.

I have to wav files already imported in Content Browser (VO_Audio1 and VO_Audio1_ENG), i create a Dialogue Wave for english version (current culture) with the ENG Sound wave, then right click on that asset and select “Create Localization Asset” seleccting spanish. Then go to Loc Dashboard but here i dont understand somethings

Where says Raw Audio Path which folder should i select?
when i click on import dialogue always appears a warning that says "The Following audio assets have been loaded by the editor and may cause the dialogue import to fail as theie files will be read-only

And obviously the audio only plays in english, never in spanish even if the culture is spanish
