RileyB_SMS 3 Report post Posted April 16, 2018 I have a fillable PDF that has some check boxes on it. When you check a box and then go to save it as a flattened PDF (for our record keeping) it unchecks the box. Its not just the one document, I have tried to make new documents on Nitro 11 and it does the same thing. We have never had this issue before upgrading to Nitro 11, any ideas? I have checked over the settings multiple times and do not see any options that would change this. Share this post Link to post Share on other sites
