I am probably not the one to answer this but, just a thought pending a response from one of the experts, if the lines following the text is for a response....try highlighting the lines and enter your data as necessary. My initial thought is that the form was not created as a form properly (otherwise, you would not need the lines following the text).

Nothing against Word but, I have always used Adobe Acrobat to create fillable forms (thus, my initial comment).
