Low Accuracy with Multilingual Option - Need Help with Vocabulary Filters Files (Spanish)

[ander-chan]

I am testing the app, but I am only getting 50% accuracy. I have activated the multilingual option. However, I have not been able to find information on how to create or locate the vocabulary filters files. Can someone provide guidance or resources on how to find or generate these files?

Thanks in advance for your help. Nice app.
