For everything to be alright, all the values from the screenshot need to meet the consistency standards.

Data redundancy check

This check looks for tables leftovers, which are created when a user deactivates a survey. For example, if you deactivate a survey, the token tables, the response tables etc., will not be automatically deleted. If you do not need the respective data anymore, use the Check data integrity function and select the items you wish to be deleted.
