the life preserver is a result of having 'image' (external component) components in your filter. remove those and you shld get just the texture showing up in your results. the life preserver image is the default image that comes with filter forge when you make and use an 'effects' filter as opposed to a 'texture' filter. texture filters do not use any imported or default image. so, remove the 'image' components from your filter and there you go.
If wishes were horses... there'd be a whole lot of horse crap to clean up!
