Adobe Acrobat DC automatically joins lines of text into a single paragraph. How do I prevent that?

Thanks for the answer. I guess it is static text. I insert three different text lines like:

Line 1:

Line 2:

Line 3:

and I would like for them to be independent text lines to make it easier to edit. Once I save the form they are automatically joined together in a single paragraph...

My question is how do I keep them as independent text lines, is there a way for Adobe not to join them automatically?
