I have just uploaded TsGui 220.127.116.11 to the site. This version fixes a bug with groups and toggles where configurations with multiple pages might not behave correctly.
Also be aware that there is an issue in the latest Windows 10 ADK where a DLL is missing. This is causing errors in WPF based applications like TsGui. See the 18.104.22.168 release notes for links to the workaround (adding the DLL back into the WinPE).
