I suspect this is because there is no lease created for fixed-address hosts - the server just bypasses all the lease logic and just offers the address. You might want to try using reserved leases (set the "reserved" flag on a lease), they go through the lease lifecycle - but just aren't allowed to be reallocated to another host.
