DHCP pool depletion with conflicts

Hi,
I am trying to configure DHCP server on 2 devices with vrrp. vrrp1 is 10.10.0.10/29 connected to a Dell N4032 core switch at 10.10.0.9/29 on which I am relaying DHCP per subnet / VLAN to vrrp1.
Statically assigned leases are working as expected but when a client tries to get a dynamic lease my leases populate with addresses from the pool and 00:00:00:00:00:00 for mac adresses with conflict.
I know there are no conflicts as I get this behaviour when I create a new subnet.
Perhaps I am missing something?
Thanks!

/ip pool
add comment=mgmt name=010 ranges=10.10.10.201-10.10.10.250
/ip dhcp-server
add address-pool=010 comment=mgmt interface=vrrp1-dhcp name=010 relay=10.10.10.1
/ip dhcp-server network
add address=10.10.10.0/24 comment=mgmt dns-server=10.0.0.6 gateway=10.0.20.1 netmask=24 ntp-server=10.0.0.6

I had proxy arp enabled on the uplink now fixed
