Missing values for Nikola's queries

I have loaded a very small HATVP dataset: small-hatvp-demo-bda.xml

I can get an abstraction, but when I query it to get the tuples (declarer name, nb of shares they have), I get mostly empty results, which is not correct because there are values in the data.

In my dataset, JF Rousset has at least 1014 shares in SA clinique pasteur, but here it shows nothing.

Has any of you already used Nikola's queries in Studio? @mmohanty @manolesc @x-TGaliz @x-SEbel

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
