Transfering out domain from Cloudflare to different provider also using NS1

Hi everyone!

I have problem to transfer out domain from Cloudflare to another provider. When I am transfering domain to this specific provider, it returns me error like this A DNS zone for this domain already exists on NS1. I tried to disable DNSSEC, unlock domain for transfering out and removed site in Cloudflare dashboard. But after almost 2 days this another provider returns me same error.

How much I need to wait for a records to be deleted from nameservers so I can transfer out my domain?
