Missing campaign dependencies

I only own the WoL campaign, but I’ve read that dependencies from every campaign should be available to use in custom maps.
The only dependencies that show up in the editor are the WoL ones, WC3, Nova, coop and ‘Glue’, despite them needing Hots and Lotv licences.

Is this supposed to happen? Not being able to use (not even being shown) the campaign dependencies?
