SQL Server Replication - Local Subscription still visible after drop?

Using a script which you can generate through SQL Server Replication, I am trying to drop the subscription and publication as part of a job:

-- Dropping the transactional subscriptions
EXEC 
    NTTMI.sys.sp_dropsubscription 
        @publication = N'NTTMI_STAGING_TEST', 
        @subscriber = N'PENGUIN', 
        @destination_db = N'NTTMI_STAGING', 
        @article = N'all'


-- Dropping the transactional articles
EXEC 
    NTTMI.sys.sp_dropsubscription 
        @publication = N'NTTMI_STAGING_TEST', 
        @article = N'CallScripterSource', 
        @subscriber = N'all', 
        @destination_db = N'all'


EXEC 
    NTTMI.sys.sp_droparticle 
        @publication = N'NTTMI_STAGING_TEST', 
        @article = N'CallScripterSource', 
        @force_invalidate_snapshot = 1

-- Dropping the transactional publication
EXEC 
    NTTMI.sys.sp_droppublication 
        @publication = N'NTTMI_STAGING_TEST'



-- Disabling the replication database
EXEC 
    master.sys.sp_replicationdboption 
        @dbname = N'NTTMI', 
        @optname = N'publish', 
        @value = N'false'


exec NTTMI.sys.sp_subscription_cleanup
    @publisher = 'Penguin', @publisher_db = 'NTTMI', @publication = 'NTTM_STAGING_TEST'

However, when I check the replication folder after the publication is gone but the local subscription is still visible (see image below). Is there something I am missing?
