Not able to save connections with custom port on Mac VPN

Hello everyone,
We're having problems with our connection profiles on Mac. The Mac computers are running the latest version of Forticlient VPN.

No matter if we enter the remote gateway with a port number (:443) or in the customize port. When we click save and reopen the connection profile the port number in the URL is gone or the check box for customize port is unchecked - without it it's unusable.
