Why some user get different Lease Expiration from the same dhcp

Hi, C9800 wlc use internal dhcp for each clients. All clients use the same dhcp server. Why some clients get Infinite Lease Expiration and other get finite lease expiration? Please see the below screenshot. Thank you

This looks for me is the DHCP Server before setup and infinity, and recently changed to expiry time  for me.

Once the infinity user disconnect and connect again new expiry time will apply

This is my assumption based on the information provided on this thread.

Lease time can be defined per DHCP scope. So, you may be on the same server but in different scope.

Thank you all for your reply. You are right, balaji. The lease has been changed by someone.

Also to be aware that if you allow bootp clients then they will get an "infinite" lease so you might want to configure:

ip dhcp bootp ignore
no ip bootp server
