No,
the problem with articles is different. You have configured items as follow (just as example):
/contract-flooring-journal/flooring-articles
So, when you call an article with URL:
/contract-flooring-journal/flooring-articles/7-interbuild-article-portfolio
These URL still match meta tag for section or category (the first item in the example above).
Please, add a dollar ($) at the end of all your URL related to sections or category, as follow:
/contract-flooring-journal/flooring-articles$
This means "end with" and the URL related to an article will not match anymore with it.
Remember that Tag Meta uses regular expressions. This is powerful, but requires a little practice.
Let me know,
