Interactiv PDF Check Box Error

Hi everyone,

I'm having an issue with exporting an InDesign file as an interactive PDF including interactive checkboxes. I have set the checkboxes using the Zapf Dingbats font. However, when I export it, the checkboxes are not working properly.

I'm currently using Adobe InDesign version 19.4. Has anyone experienced a similar issue or knows what might be causing this problem?

Thanks in advance for your help!
