Switch to any other frontstage and then switch back to the main one.
Select a tool that doesn't have any tool settings - distance measurement for example.
Notice that empty tool settings message doesn't pick up correct active tool in label and still shows the first one that was selected on iModel open, so in this case it'll always be "Select Elements" tools.
To reproduce the issue:
Possible fix: appui/ui/appui-react/src/appui-react/widget-panels/ToolSettings.tsx at master · iTwin/appui · GitHub Add a callback based on activeToolId to change emptySettings correspondingly to this function.
Thank you!
