Could it be there are other leases in that file which are still valid?
Or other files? For example, my Debian 9 box has these files:

-rw-r--r-- 1 root root 1046 Jan  7 09:44 /var/lib/dhcp/dhclient.eth0.leases
-rw-r--r-- 1 root root  525 Feb 10  2013 /var/lib/dhcp/dhclient.eth1.leases
-rw-r--r-- 1 root root    0 Aug 23  2018 /var/lib/dhcp/dhclient.leases

So for me the valid lease is actually in
/var/lib/dhcp/dhclient.eth0.leases and dhclient.leases is empty and
dhclient.eth1.leases is a blast from the past.

I'm not using NetworkManager though. NetworkManager might have its own
idea about gateway address.
