LongQuestionResults - Stale Data

I have noticed that the LongQuestionResults table retains old data even when a computer no longer returns a data set that would be considered “long”. How do we cleanup the LongQuestionsResults table to remove stale content? The SQL table is not in sync with what i see in the console, the console looks good.
We are on v 9.5.12.68
Is this a bug ?
Any ideas ?

Every entry in the LONGQUESTIONRESULTS table is an extension of a correspondent entry in the QUESTIONRESULTS table and is removed when the pair entry in this table ( i.e. the property ) is deleted as well only ( logically from the console, then physically running the AuditCleaner tool ).

The ‘effectiveness’ of the entry in LONGQUESTIONRESULTS depends from the ResultsText column in the QUESTIONRESULTS table, if it is NULL or not. So that in all rare cases in which the entry in the LONGQUESTIONRESULTS table became no longer required, everything continue to work properly and don’t need to delete the entry in the LONGQUESTIONRESULTS table.

thanks, just what we suspected. thanks for the clarification.
