Did you set external_mac for NAT record? This is usually done when scale-out model for floating IP is used (I don’t know the exact name for the feature, where static NAT is done directly on the host, where the VM/container resides.) If yes, try to remove external_mac from NAT record or disable this distrubuted NAT feature.
Maybe the root cause is that NAT record is using MACIP pair, which is not programmed to Hardware_VTEP db ucast_macs_remote table.
