Duplicated rel nofollow

Hi,

Very useful plugin.

However I noticed that if I had old links manually edited like
<a href="https://www.hydrotronik.pl/" target="_blank" rel="nofollow">Hydrotronik</a>
in text editor, it results in
<a href="https://www.hydrotronik.pl/" target="_blank" rel="nofollow external nofollow" class="ext-link">Hydrotronik</a>.

Article is https://zschocianow.pl/stanowiska-badawcze-dla-feerum-s-a-zespole-szkol-chocianowie/#przedstawiciele and link in Piotr Wi?niewski – Hydrotronik, in first bullet of second list under Przedstawiciele header 2.

My settings: zschocianow.pl/files/Better-WordPress-External-Links.jpeg

It would be nice if you could fix it by strpos or something.
