Zoho Expense Report needing a "Permissions Password" to edit a pdf of the Report?

I'm the Administrator of our Zoho Expense & Zoho Books, and have never set up a "Permissions Password"  But when i create a PDF of an Expense Report and go to edit it using Adobe Acrobat (I need to add a text box to the Report), it doesn't allow me to edit it without a "Permissions Password"   How do i resolve this? Anyone else find a solution?
