Frequent Itemsets and Association Rules must be run on basket data. Open widget Datasets, find Foodmart and try it.
Data in attribute-value form (like the one that you use) must be used when we don't want to treat a "0" value as special. They find relations like "didn't buy bread -> didn't buy ham", and there are naturally many more of them. This is by design.
In your case, 0 is a special value, so the data must be given like this: https://file.biolab.si/datasets/foodmart.basket.
