Sidebar item not always aligned to selected activity

Start latest MaintenanceTool coming with OpenSource Qt version.

On page deciding the main activity click to radio buttons as at first, then second, then third, then second, then first etc. in loop. After click to next button review how are changed the items in sidebar - uninstall doesn't change it but re-curring to update offer uninstalling activities...

(I didn't try it on Windows)
