Multiple documents in workflows

I create workflows for my company.  To keep down the number of workflows, I have designed them with the facility so that users can choose the documents they need for their particular purpose, while keeping them still mandatory.  This worked well until very recently.  Now when using these workflows Adobe Sign offers a default which the user has to 'delete' before choosing the correct one, but the offering of default does not seem to be logical.  ie. for contracts for 1, 2, 3, 4, 5 or 6 signatories, the default is 4.  What has changed and is there a fix for this?
