Foreman - Setting-->Subnet

**Foreman and Proxy plugin versions: 1.23

I am unable to save the interface configuration on the host. getting the below error.

Error:

Unable to save * Create DHCP Settings for foremanstage.example.com task failed with the following error: ERF12-6899 [ProxyAPI::ProxyException]: Unable to set DHCP entry ([RestClient::BadRequest]: 400 Bad Request) for proxy https://foremanstage.example.com:8443/dhcp

I am creating new staging environment as production. under subnet configuration I am unable to see the DHCP option as it shows up in production.

This button will only appear if the subnet has IPAM mode set to DHCP.
