V4.1: 1265, or 1586 features?

[split oyster]

I have a question about V4.1 features. On https://numer.ai/data/v4.1 you say that there are 1586 features. When downloading features from the V4.1 feature sets (napi.download_dataset("v4.1/features.json")), I am getting just 1265 unique features. How do I get all the features please? Thanks

My code:
napi.download_dataset("v4.1/features.json");
feature_metadata = json.load(open("v4.1/features.json"))
feature_cols = feature_metadata["feature_sets"]
unique_features = set(feature for sublist in feature_cols.values() for feature in sublist)

The first section "feature_stats" has all 1586 -- is that what you're looking at?

oh thanks!

that's what I do:
all_features = feature_metadata["feature_stats"].keys()
