I struggled to find my Unstarred automations recently. Below is the feedback I gave Summer and she said to share here:

The UX isn't very clear in my opinion. When you click the "add filter" why doesn't it have unstarred? It's not clear you should click on

the word Starred to see more options because there is an X next to Starred which looks like the only action available. When I toggle sidebar it says no filters available. Totally unclear how all those buttons / options work together to help you see your automations. If I click the "X" next to Starred the only way to access Unstarred automations is to refresh the page

and then click Starred...
