Checkbox values visible in Preview in Mac but not on Adobe Acrobat Pro

I would really appreciate it if someone can help me here.

I am trying to AJAX post this form data from a Python-Django based web application and generate a PDF file. This form has some checkboxes that can be answered and the values for these fields get picked up in the payload in the AJAX post.

Now, when I try to open that generated PDF file using Preview app on Mac, I am able to see the checkbox marked correctly; I can also see the checkbox marked correctly when I open the downloaded PDF in Google Chrome web browser as well.

However, when I try to open the same file using Adobe Acrobat Pro, I cannot see those check marks for those checkboxes. This is only happening for checkbox values and no other fields.

I have tried to check that the field name attribute on both the Adobe Acrobat Pro (using Prepare a Form section) and my .HTML file where I am defining that field in my web application and they both match up.

Can someone please tell me why this is happening? If this is a known issue, what is a good work around for the same?
