Microsoft Forms Spreadsheet not updating after Sensitivity Labels applied

We have created a Microsoft Form on a SharePoint site to collect sensitive data. Our security team wants us to implement an access control sensitivity label applied to the spreadsheet tied to the form data in the even it is accidentally shared. 

We created an access control sensitivity label scoped to the few members of the SharePoint site and applied it to the spreadsheet and have verified access is indeed blocked if spreadsheet is shared to anyone not allowed in the label.

The problem occurs when new data is entered into the form: the spreadsheet no longer updates with new data. We can sync the data to a new spreadsheet and the new responses show up with the old. But again if we apply the label, no new form data is updated.

How do we modify the label so that when applied to the form's spreadsheet, new data is allowed to be added?
