¿Qué causa este problema?

You are trying to reverse deletion of a schema. However, the system
has not found the end of the schema, i.e. there is no line containing
the text 'END OF COPY' and the name of the subschema. This can
occur for the following reasons:
You have never deleted this subschema.
After deletion, you deleted the line containing the end indicator.
In this case you must also delete the other lines of the subschema
from the Editor and activate the line with the COPY function.
