Variables not being processed?

I’m building a new workflow and unexpectedly, in all the places where I would expect to have the variable inserted, I’m just getting the variable holding spot.

For example, here are the global objects coming into the create ticket, and I would expect to be able to use {{global.AlertDetails.activity}} or {{global.SHORT}} (if I just want the default [0] entry)

instead I get the description set to the literal placeholder.

or when adding a note, you can see it with multiple entries:

Did I accidentally toggle something off to not process these?

As a side, I know that I always struggle to get the list of variables to appear. When I start typing {{, the globals are never on the list (unless the global was defined in that rule). The custom one are sometimes there, but not always… seems like it depends if the rule has been saved previously or not. So I usually wind up copy/pasting them to avoid any typos.
