Can you update your step by step instructions to have more detail? I can recreate the bug from the description but I'm not sure if it is the same approach as you. See my attempt below:

openstack port create port1 --allowed-address ip-address=10.0.0.10 --network private

# use subnet id for '10.0.0.0/26' subnet in the following command

$ openstack port create port2 --fixed-ip subnet=2e3b3133-7e67-4a3b-9b1d-6d25238788d2,ip-address=10.0.0.10 --network private
