```` markdown not rendering with content tabs

Can someone tell me what I may be missing?

I'm not sure, can you provide some configuration information?

You need pymdownx.superfences. You do not need to specify pymdownx.highlight and SuperFences will automatically use it. You really only need to specify it if you are changing one of the global settings, or are not using SuperFences, but since you are trying to render fenced code blocks, I'd enable superfences.
