Why this happend? Thanks
Obviously, as I already told you, you have changed something in the settings of Protege - because the default namespace for the creation of new entities doesn't change by chance.
File -> Preferences -> New Entities tab -> Click on Active ontology IRI (or change the Specified IRI to the one that you want)
By the way, you should use your own namespace and not that one that is auto-generated by Protege.
