PDF fillable form not displaying field data

Greetings, 

I have an employee who is receiving fillable PDF forms for work via email. When opening file preview on the form within Outlook Desktop the form is displayed and the field data is in the fields designated. When opening the PDF with Reader or Acrobat Pro the forms field data is blank. Clicking on fields to highlight test does not reveal anything, and trying to insert a space and delete the space within the field nothing is revealed. When opening the file with MS Edge, all the forms field data is then viewable. I have another employee that was able to open the same form using their Acrobat XI and was able to view the field data as well. With opening the PDF's via Edge, we are able to print form to MS Print to PDF and upon doing so and opening with Reader or Acrobat Pro the form data is viewable.  I have checked the versions of Reader and Acrobat Pro and both are up to date as well. Any suggestions are greatly appreciated.
