I am using the ‘Post (Lists)’ Element in the Page Builder.
I have it displaying all posts on the page without a problem, looks great. However, I only wish to display posts in a certain category I’ve defined (‘Articles’) in the list and not every post on the site.
How can I do this? I’ve looked everywhere I can think of and I’m sure this must be possible, but cannot find a control to achieve this.
Cheers 

Please see a screen shot of what I’m talking about - other than ‘Edit’ being present there is no indication a Taxonomy has been set and what it is (such as the category name, so if I’m understanding you correctly, this should display as ‘Articles’ instead of ‘Edit’):
