Demotion of 2016 Domain controller from Sites and Services

Hello Expters,

We have multiple 2016 Domain Controllers

We have demoted one DC from GUI and it was successful , But after removal of DC , this DC still shows in Sites and Services .

So ,  any Idea why its not deleted from Sites and Services , 

Did I miss any steps for demotion ?

Thanks for your help.
