drop article does not clear records from MSreplication_objects

I have simple transactional replication set up.  One of the publications had 3 articles.  1 of those became unnecessary, so I did:

EXEC sp_dropsubscription @publication =  'Pub_A', @article = 'Art3', @subscriber = 'Sub_Server'

EXEC sp_droparticle  @publication = 'Pub_A', @article = 'Art3' 

This seems to do exactly what I want, which is to keep the publication, but just remove Art3 from the subscription, and then remove Art3 from the Publication altogether.

I understand that the Art3 table will still exist on the subscriber db, and that I have to drop that.  However, at the subscription db, I run

select * from MSreplication_objects
where publication = 'Pub_A' 

This returns 3 replication procs for each of the 3 articles, including the Art3 which I had dropped.  Is this a problem?  Do I need to delete the Art3 rows myself?  I don't think this was ever fully documented, for such a simple process as dropping an article.

Thanks for your insights.
