Remastered in Spanish uses old audio instead of new audio

So, my copy of SC Remastered in (European) Spanish uses the unit speech, dialogues, alerts… of the old 1.16.1 version, not the new (European) Spanish remastered audio.
What can I do?
The Remaster is toggled on.
Why do I post here instead of the Spanish forums? Well, the post rate is not great.
