Using fill & sign, text boxes replicate in other unwanted places

I am currently trying to fill a large 200 pages pdf using the fill and sign feature on Adobe Acrobat. The pages that need filling are only about 25. From page 38 to page 65 of the pdf. The fill and sign feature works well, even auto-detecting the form fields and checkboxes and typed text appears as it should be and is editable.

The issue I'm having is the created textboxes reappear randomly across other pages of the pdf and to add, not in fillable fields, just randomly elsewhere, and in different pages.

For example if i fill in the text "Sunshine Corporated" into the field asking for the company name, which is actually needed on almost every one of the pages to be filled, that text box will spawn elsewhere in the document, severally. Even in pages before the one filled. And just randomly. Pg.2, 14, 52, 78, 121, 122, 180, for example. Not even in fillable fields. I'll just be scrolling through and finding textboxes I filled in the forms showing up in singularity in other places of the pdf.

Everytime I create a textbox to fill a field in the form, I have to scan through all other 200 pages to ensure there are no unwanted textboxes as it is really a very sensitive document. It really is frustrating.

I have tried checking for this issue online but seems only I have it. 

Please help.
