Displaying Code with Syntax Highlights

I followed these steps https://poshsecurity.com/blog/powershell-syntax-highlighting-with-squarespace

and within my blog it works ( while I'm in sqaurespace) See first attached pic.  But when it is published it looks like normal code without the syntax highlighting..  I've tried a code block to call out powershell and I've used markdown like in the tutorial and both have the same result.  Any ideas?

----update I notice when I hit refresh on the page it displays properly----

So did you solve?

Not without disabling Ajax which can impact the rest of the site 😕
