Some data are not loaded correctly into WDQS. There are several tickets about it, specific example: wds:Q58696890-2376E531-DD35-4851-AE50-5D2F0770BCED has different data on:
'wdq5', 'wdq4', 'wdq23', 'wdq8', 'wdq24', 'wdq25'
wdq6', 'wdq21', 'wdq22', 'wdq3', 'wdq7', 'wdq26', 'wdq10'
and another different data on wdq9.
The difference is that the statement in the former is missing rank, type and reference.
