pdftk dump_data_fields不包含复选框标签

I am using pdftk to dump the datafields from my editable PDF. I want to get checkbox field names, or you can say labels for the checkboxes. The problem is that the file generated by dump_data_fields doesn't return the exact checkbox labels; instead it shows the checkbox description.

For example:

FieldType: Button
FieldName: ResidentialStructure_Basement_FoundationFinishedIndicator_A
FieldNameAlt: Check the box (if applicable): Indicates the basement/recreation room is finished. 
FieldFlags: 8388608
FieldJustification: Left
FieldStateOption: 1
FieldStateOption: Off

FieldType: Button
FieldName: ResidentialStructure_Basement_FoundationWalkOutIndicator_A
FieldNameAlt: Check the box (if applicable): Indicates the basement/recreation room is a walk out. 
FieldFlags: 8388608
FieldJustification: Left
FieldStateOption: 1
FieldStateOption: Off

The real labels of these 2 checkboxes in the PDF document are finished and walk out, but we only get descriptions of these checkboxes as shown above in FieldName and FieldNameAlt.

Is there any way to get exact checkbox labels using dump_data_fields or any other property of pdftk?
