Siri Shortcut management

Hi all,
I have quite a few devices dotted around the house and recently created the Siri shortcuts on the APP.
One of my bulbs stopped responding so i replaced it with another one from a different location, reset it and named/assigned to new room.

The old Siri shortcut doesnt seem to activate the light i replaced, even though i have assigned it to the room so i thought i would record a new siri shortcut with the same phrase but it wont let me.

Where does the siri shortcuts get stored ?
I want to re-record the same phrase for the room but it wont allow me.

anyone ideas?
