Ruby on rails 使用PDFtk填充的PDF表单上的复选框显示不一致

我正在用基于PDFtk的PDF forms（）gem在rails应用程序中填充PDF表单。文本字段的工作方式与我预期的相同，但复选框字段的工作方式不同。这些框在Chrome中显示良好，但在Preview和Mail中，复选框字段显示为空

class FormsController < ApplicationController

def acord25
  @policy = Policy.find(params[:id])
  pdftk = PdfForms.new('/usr/local/bin/pdftk')
  # find out the field names that are present in form.pdf
  pdftk.get_field_names 'lib/pdfs/acord25.pdf'

  # take form.pdf, set the 'foo' field to 'bar' and save the document to myform.pdf
  pdftk.fill_form '/lib/pdfs/acord25.pdf', "acord25.pdf",

TL；DR：复选框在Chrome中显示，但在预览或邮件中不显示。

我感谢任何关于问题所在的帮助或线索。谢谢大家!

结果显示PDF表单已损坏。必须重新创建表单，而不是PDFTK问题。

否？如果我说“请”怎么办？
