Missing feature when using load_data() to load audiofolder

Hi, I am trying to custom an audio to text dataset but the dataset load on colab seems missing the text feature. I jsut followed the doc exactly and made a test dataset to test what the problem is, but the dataset loaded still recognize audio as a feature only.

My test dataset path is: User1115/smallTest
Does any know what the problem is?

Also, I tried to use data_dir to load dataset, but got an error
