Adding multiple Rich-text & image-with-text to a page

This is what I tried to do, but when I have written something in the 1st rich text section,

it has duplicated it in the 2nd rich text section

which it will not let me change the 2nd section

eg.

code-

{% section ‘rich-text’ %}
{% section ’rich-text’ %}
what I’ve written in admin-

about us blah blah …

about us blah blah …

it won’t let me change the 2nd rich text

do I need to type a code that basically says (don’t duplicate) or something?
