Check boxes won't stay checked

[Jason28068293xgjd]

I recently created a form using InDesign 2023 and exported it as an interactive PDF.

When I open in it in Reader and I select a checkbox, a check mark appears, but when I navigate away from it (either by clicking elsewhere or hitting TAB) the check mark dissapears. And if I save the form when the box is checked and then reopen the form, the check mark is gone. What am I doing wrong?

Hi Jason28068293xgjd,

Thank you for reaching out.

As you have created the PDF form in Indesign, we would like to check it.

Would you mind sharing the PDF form with us so we can replicate the behavior?

Share the application and OS version details as well.

Thanks, 

Meenakshi

Thank you @MeenakshiNegi. The PDF is attached.

Re: application details, I actually misspoke in the original post. It was created a few years ago in InDesign version 14.0.2.324. I am now using 18.0.0.312.

Here are OS details:

Edition Windows 10 Enterprise
Version 21H
OS build 19044.2486
