I have 2 servers, A and B. A is ns1 and B is ns2. These two nameservers are in cluster.

I have a client.com hosted in server B. I have made A record for subdomain.client.com to point to IP address outside my servers. After the change, within few hours, something magical happens in server A (ns1) and the A record for subdomain.client.com starts to point to the IP address of server B. I have not done this change. Still, in server B (ns2) that subdomain.client.com is pointing to the right IP address outside my server.
What is causing this and how to fix it?
