Domain Redirection Issue

Dear Cloudflare Dev Team, Context: I purchased a domain nahyan.pk from my local registrar hosterpk.com This registrar didn't allow me direct access to dns record setup instead I had to generate some kind of tickets for the changes. I pointed nahyan.pk to my server ip address, it was working fine. I needed free ssl certificate for my domain and heard about cloudflare providing for free. I setup proxy for my domain nahyan.pk and I got the free ssl for my domain. I decided to abandon the domain nahyan.pk and asked the hosterpk.com to remove the dns records from their end (which they said they did) and purchase another one from cloudflare itself nahyan.biz. I added the the same server ip address to this domain. Issue: When i try to visit my nahyan.biz domain it resolves the ip address correctly but after that it changes it to nahyan.pk I have attached a picture from wireshark to show the dns record lookup please guide me how to fix this issue 🙂
