Port Forwarding rules not saving

I currently have an Orbi RBR750 (firmware V3.2.16.6_1.4.4) and anytime I try to add a custom port forwarding rule it does not work.

When I hit the add custom service button I am taken to the Ports - Custom Services page where I type in a service name, select the protocol, type in the external and internal port numbers and also select the internal IP address. After I do all this I hit the Apply button where I am then taken back to the initial port forwarding page but there is no option to select the rule I just created.

I can create custom rules under port triggering with no issues, but unfortunately port triggering will not work for me and I need to get port forwarding working, any help would be appreciated.

P.S I have tried to contact customer support but as this was purchased more than 90 days ago I did not get any help. If this is the wrong place to post for customer support please let me know where I can go to get support for a device thats less than a year old.
