OpenVPN Client [Legacy] Unable to delete client

[Apex]

I'm attempting to delete a legacy client as I no longer need the VPN tunnel. I select it, click on the "delete selected rules" which produces a pop-up of "Do you really want to delete the selected clients? No / Yes

I click on Yes, and it just sits there. It does nothing. I've deleted the interface associated with it, the gateway group the outbound firewall rule. There isn't anything associated with this client now and for some reason it will not delete using the GUI.

Is there a way to do it via the shell?

Rebooted the firewall and was able to delete the client.

It went into a non-responsive state via the GUI when attempting to delete it, forced a reboot via SSH and it came back up. Client was still there, hit delete again and this time it removed it.
