HasStandard

So, I am trying to reference standards in an info box

I am labeling the standard as:

[[20181219 HasStandard::A random standard]]

[[20181219 HasStandard::Another random standard]]

Then, trying to call the standard using:

{{#show: {{PAGENAME}} | ?20181219 HasStandard}}

I have embedded the actual code below

A random standard

A random DEFCON

Now, below here, it should show the standard, but I do't seen anything.

A random standard, Another random standard

But for some reason, it won't show the standards.

What am I doing wrong?
