In the latest stable release (v1.2.7), clicking on the Install Version field in the Application Information will generally reset the value to 18.104.22.168, if this is a project which has been saved & re-opened.
Even when the value doesn't get reset (i.e. if you've changed the value already in the current user session), there's no way to modify the values in this field with the keyboard. Instead, you have to use the arrows to increase or decrease the value of each part of the version number. If you click directly on the numbers, hoping to edit them with the keyboard, the mode toggles from display to edit, but you can't type any values.
