Can't show All Apps touchbar when focus in on another app

I have set up buttons for the All Apps group. All buttons are set up to only show when Options key trigger is shown.

I also have buttons set up to show for an app called Slack. When I go to Slack I see all those buttons come up automatically without pressing a trigger. When I press Options to trigger the All Apps buttons I don't see them.

How can I see All Apps buttons when I press the Options key?
