A questionaire used as task in Journey configured as SUM in journey doesn´t shows the result

Summary:

The client has asked to create 3 questionaires as task in journeys, those questionaires are configured as SUM option for calculating, when test it on preview it shows the result, but it doesn´t shows it in the task when they finish the questionaire. The reason that we are using this option (journeys- task questionaire) is that they want to minimize the clicks for the users, and get the resulting number as soon as possible, and go to the next questionaire for less timing outs possible.
