I finish a line and press enter twice to show one line of space between paragraphs.

However, when I copy and paste to Wordpress for example, it shows 2 lines of space.

If I even copy text with 1 line of space, into Zoho Writer, it will show all lines together with no break.  If I go to the end of each paragraph and make a break,  then when I copy it back, there is 2 line breaks again.

Very frustrating and I hope there is an answer.  Thank you.
