Spin buttons on formatted fields don't show on exported PDF form

Creating a fillable PDF form as a character sheet for a game. Stats have fillable forms next to them, some of these are “formatted fields”, General number format with a spin button. When I export the PDF, the spin buttons don’t show up nor are they usable. Any help would be appreciated, I want the players (form fillers) to be able to use/see the spin buttons.
Thanks in advance.
