Now overwrite the new entries with the required values

What causes this issue?

You have executed the "Paste" function for the entries that were cut or
copied previously.
As you used the entries within the same node, you have numerous entries
with the same name.
To avoid this, you must overwrite the keys with the new characteristic
values.

System Response

release.
If the entries have not been changed, a suitable error message is
generated.
