How to remove encryption key for an explicitly encrypted table

I have some tables that was created with explicit encryption previously (Encrypted=yes, encryption_key_id=1), and now I have decrypted them (alter table <database.tablename> encrypted=no), but the data "`encryption_key_id`=1" still shown in the create_options column of information_schema.tables of the tables. I have also set innodb_encrypt_tables to off.

How do I get rid of the create_options data in information_schema.tables
