Slices not showing up in Dashboard view dropdown

[WillA108]

Hello!
I’m trying to make a dashboard view that shows all of the maps for all 8 of the delivery routes on my app.
I created a slice for one of the sheets and it works beautifully. I copied it and changed the target sheets and it looks exactly identical.
The other 7 slices don’t show up in the drop down for the Dashboard view when I add additional entries.
Any ideas? Tried reloading.
