Fillable fields disappearing in random ways

At my work we are trying to transition to paperless data packets. As a part of this we have made several fillable forms. They were created and are combined (using the combine tool) with other PDFs, all in Adobe Pro. 

 

The problem is that it seems anytime you combine or save any PDF that contains fillable fields there is about a 5% chance that some of the fields will disappear, including ones that have already been filled in. For drop down boxes, they may appear to be there but there is not way to click on them. The outlines of the fields are still visible if you go to the prepare form tool, but their contents have disappeared. It has been very frustrating.

 

How do I prevent this from happening?

Yes, how was the second "dissappeared" file created?  Since it is not a combined file.  Exactly what tools (apps) were involved?

 

The fields appear to have dissappeared because the parent objects for some of the fields have been removed from the AcroForm object. This could result from pages being copied to a new doc without copying the associated document level data.

How are you combining the files? Which version of Acrobat are you running? The two files you've attached have the same number of pages, so they are not the results of adding in another page or file. How was the file created? What was the exact process to go from the first one to the second one?

Good questions.  In the document properties, one shows Microsoft Word as the PDF Producer and the other shows Adobe Acrobat.
