Fillable Checkbox in Adobe Acrobat Reader DC

I have fillable forms that were created in Adobe Acrobat Pro 2017 (Version 2017.011.30106).  I used the default checkboxes from Acrobat Pro within the documents.  The "check mark" shows clearly in the box while in Adobe Acrobat Pro.

However when I try to open the same form in Adobe Acrobat Reader DC, all I get is a small dot in the check box (no check mark).  I also get an error message when I open the PDF stating "Cannot find or create the font 'ZapfDingbats'.  Some characters may not display or print correctly."

This is a recent problem which only arose when my company upgraded to the most current Acrobat Reader DC (version 2019.008.20081) around Nov 6.

I suspect that Acrobat Pro 2017 is using the ZapfDingbats font as a default font to show the mark in their check boxes.  But that font apparently is no longer available in the latest version of Acrobat Reader DC.  Can someone confirm and suggest a way to fix the checkboxes so that (in Acrobat Reader DC) they actually show a check mark or box or something besides a barely seen dot?
