Bug: nested tags in shortcuts not updating

[kd01 3]

Some of my shortcut items are tags, and some of these have nested tags underneath them in my hierarchy. When I click on the down-arrow next to the "mother tag" all the babies appear. All well and good. But when I add new subordinate tags to these existing ones, even after syncing Evernote doesn't show these new tags in the drop-down menu. I have to delete the tag from Shortcuts and re-add it to make the new one appear. This seems like a bug.
