Smartthings with Sonos: volume is too loud. Resume original level?

When you trigger a sound, for example dogs barking, I have the volume set at 80%. From what I remember, it stays at 80% so when you play sonos again, its blaring loud at that same level. No way to have it go back to the original volume before the trigger?

It says to temporarily change it but it doesn’t work. It appears to keep it at that level. Any idea how to change this?

It’s only lowering by 2 for me…
