pdf-form-fill radio buttons dosnt fill when no default value is provided

[smettu007]

Thanks for this awesome library author.

I tried to fill radio buttons pdf sample pdf created in adobe acrobat pro and they arent working when there is no default option selected for radio button group(i named it Group7).

Initially when i try to get field values using PDFDigitalForm class {"Favourite Colour List Box": "Red", "Group9": null}radio button Group9 is null, since there is no default value selected.

However when there is a default radio button selected then the radio button filling works, but will there be any fix for not being able to fill the radio button when there is no default option selected?
