Hi @Success_Vera this issue was raised a while back, the zindi team decided to rather remove the audio files not in the clip directory from the sample submisssion so we wouldnt run into errors like ''missing data values' when submitting csv's .

so inorder to iterate faster i would suggest you write up a short code snippet to identify all test files audio names not in clip directory(26 files) and drop these audio ID's from both test.csv and samplesubmisssion.csv

Hope that helps
