Hi,

This behavior happens sometimes in Odoo when the UI doesn’t immediately refresh after a record is deleted. On the first click, the record is actually deleted in the backend, but the view is not updated right away, so the record still looks visible. When you click Delete again, Odoo tries to remove it a second time and raises the error “Record does not exist or has been deleted.” The solution is simple — just refresh your browser after deleting, and the record list will reload correctly, showing the updated data without confusion.

Hope it helps
