Tomb of Annihilation Not Visible in Compendium Settings

The Tomb of Annihilation (ToA) is not available to select in Settings Compendium Settings, and consequently backgrounds etc, are not available in the charactermancer (using the 5e OGL). I am certain I have it on my "Owned" list and I can see other WoTC supplements available in the Compendium Settings. It used to be present as i know I used some backgrounds from ToA for characters in the fairly recent past. Any ideas?

I'm pretty sure that Tomb of Annihilation pre-dates the Compendium treatment that later modules have gotten and is on the list of older products being updated. Out of the Abyss and Tyranny of Dragons are examples of older modules that have since been updated for Compendium access.

Hmm, maybe my memory of using one of the backgrounds is faulty, I may have just used it elsewhere then. Hopefully it will happen one day.
