"Document" versus "agreement"

I'm pleased with Adobe Acrobat Sign. It is a breeze to get documents routed and signed.

I am perplexed, however, with the application's apparent conflation or seemingly indiscriminate use of the words "document" and "agreement"; as if these words are synonymous (see my Teams add-in examples below). I believe one would assume, for this application, that all agreements are documents, but not all documents are agreements, but that is not how this application appears to work.

It seems to treat everything you run through it as an "Agreement," and as confusing as this is for me, I can only imagine how frustraing it might be for someone a little less familiar with the program.

Perhaps some development time could be invested in cleaning up the user interface so that terms are more intuitive and consistant. I want to get documents signed; some are agreements, some are applications or forms, and some are just memos.  But they are all "documents."
