Text Fields: Multi-Line Data Entry

     I am attempting to fully convert my office to a paperless process and we have several forms that Adobe Sign/Echo Sign has been really helpful in setting up to be filled out digitally. Then I ran into a problem with the text fields. I have them checked for multi-line data entry as the forms require an open ended and at times lengthy response, but there doesn't seem to be a limit to how much text they can put in as at times it goes completely off the page unable to be seen when reviewed. This has caused a major hang up in our transition and I've been unable to find any particularly useful information on how to resolve this issue. I'm hoping it's a relatively easy fix that I'm just ignorant to. Help would be much appreciated!!
