Yes, just one way of configuration should be used
ok, it’s fine now.
all saved entities are saved on saver.save and well restored.
saver.save_2 is still displayed but not used.
perhaps add a comment on https://github.com/PiotrMachowski/Home-Assistant-custom-components-Saver to warn : never add in the YAML if using UI (but maybe i’m too noob … 
)
thanks.
