Can someone explain wrong output for clicking first two elements of the page from this code?

Question

Get unique selector of clicked HTML element https://code.sololearn.com/WMAZk7B2MOk9/?ref=app

Answer 1

I found the solution: instead of using ' ' (space) as separator between nested levels of selector should use '>'. So selectors look like BODY>:NTH-CHILD(1).

Answer 2

What incorrect output?

Answer 3

For example, if you clicked the "First paragraph" it outputs:
=================
You've clicked "First paragraphGrandchildGrandchildSecond div header". It's unique selector isBODY :NTH-CHILD(1)
==================
But should output just:
++++++++++++++++++
You've clicked "First paragraph". It's unique selector is BODY :NTH-CHILD(1)
++++++++++++++++++

Why there is other elements content?
