Ik heb het schema proberen te maken op de preview, maar als ik een schema integrate maak en als template het integrate cohorts staging template kies dan zie ik wel dat er tabellen aangemaakt worden, maar het resulterende schema is leeg.

As far as I can tell this is in line with what we discussed. Preview works again.
Some warnings about missing fields in demo data though.
