Installer Missing OSX and IOS install options.

Hi, I'm trying to install sgcWebsockets (Latest Beta) using the installer on a fresh Delphi 11.2.1 install. Upon choosing the platforms I everything I have chosen is there except for IOS, OSX and Linux. I have installed the IOS, OSX and linux platforms in Delphi but sgcWebsockets doesnt give me the option to install them.

Is there is something I am missing?.
