How to remove all the underlining from links - custom code only working for some

I have the custom code below to remove underlining from all links on my website. For some reason it has stopped working for some links. So I have some pages with multiple links where some are now underlined, and others are not. My footer links remain without an underline.  

I also have a page where there is suddenly an underline, in a different colour, under two words, but there is no link behind those words!

What is going on? And can anyone help?

Code:

a {
  text-decoration: none !important;
}

Can you share the page link?

These are the pages with some links underlined and some not:

https://www.creativeprivacy.co.uk/points-of-view/your-data-protection-new-years-resolution-write-in-plain-english

This page has two links, both underlined:

The second link above is also the page where the words 'plain English' have been randomly underlined in turquoise.

Wonderful! That worked for removing all the link underlines - thank you!

I just have the random turquoise underline left now.
