Modifying forms after they've been made fillable

I'm using Adobe Acrobat DC Pro along with Adobe LiveCycle Designer ES4.

The document I'm working with was created in Word 2013 and then converted to a pdf.  In Acrobat, I converted the pdf to a fillable form.  Once it was fillable, I modified it in LiveCycle.  Right now, it's a fillable, save-able form.  I would like to modify the document.  When I pull it up in Adobe, it tells me that it has to be edited in LiveCycle.  Once back in LiveCycle, it's wont let me change anything.

I've attached a copy of them fillable document and highlighted the fields and text (in the red box) that I want to delete from the form without having to start over with a word document, delete the fields/text and then convert to pdf and make it fillable.

Thank you VERY MUCH!
