why do my i539 petition status says name was updated ?

My spouse’s employer applied for H1b extension in premium on feb 27 , on march 6 the premium check returned , they sent it back again accepetd and the petition got approved on march 10 . I had sent my H4 extension along with that petition and now my status says on feb 27 name was updated . i am confused , how long will they take to process it ?

well , a follow up . it got approved on March 13
