Updated document uid still returning data for the original uid

[eluxenberg (Eli Luxenbberg)]

I am querying by document id and am trying to migrate some urls with redirects. I don't have any issues with that except that for existing documents my uid query is still returning the old page even though I have changed the document uid. I see that the slug attribute is deprecated in the documentation, but I am still seeing it in my v2 requests and am wondering if that is the cause of the document still returning even after I update the uid. I don't see a way to remove or edit the slug in the UI. Please let me know if that is the issue or if there is any way to update the slug either via the UI or programatically.

query.custom_page_:  OLDUID
{
  id: 'IDHERE',
  uid: 'NEWUIDHERE',
  type: 'custom_page',
  href: '',
  tags: [],
  first_publication_date: '2020-09-08T21:05:47+0000',
  last_publication_date: '2021-01-06T09:26:19+0000',
  slugs: [ 'ORIGINAL UID HERE' ],

We have discussed it in this thread:

I changed the UID, but page with old UID is still active?

@marcellothearcane I am not sure if this will solve my problem. My client creates a lot of unique landing pages which he duplicates previous pages and he changes the URL. So for example, he has a page with URL "/linkedin-proposal", he sends it across, he makes the call/deal and then 5 days later, he wants to create a new page called "/microsoft-proposal" which is almost exactly the same as the linkedin proposal page, but with different copy. The problem is that the old linkedin proposal page …
