Align greyed out for text, and in prepare form

Hello-

I designed an invoice in InDesign, and made several interactive text fields. Exported as interactive pdf. Most sections need to be right aligned text. When opened in acrobat, all text fields are left aligned, and the align option is greyed out. Not seeing any options for alignment in prepare form text field properties, and in prepare form the align tool is greyed out. No updates needed, 20.013.20074. 

Thank you
