~16, 000 backup leases added to dhcpd.leases when implementing failover

When converting a single dhcp server to a failover configuration a large
number backup leases were added to dhcpd.leases.
Here is the config:
subnet 10.63.0.0 netmask 255.255.0.0 {
filename "/pxelinux.0";
next-server 10.60.0.107;
option subnet-mask 255.255.0.0;
option routers 10.63.0.1;
pool {
failover peer "dhcp-failover";
range 10.63.128.1 10.63.255.254;
}
}
The leases start around 10.63.191.100 and go to 10.63.255.255. An example
lease is
lease 10.63.191.171 {
starts 1 2014/09/15 23:06:08;
tstp 1 2014/09/15 23:06:08;
tsfp 1 2014/09/15 23:06:08;
atsfp 1 2014/09/15 23:06:08;
binding state backup;
}
Is this normal? It didn't seem to happen for other subnets.
How can I safely remove these leases?
