TouchMenu kills my settings page

I really prefer TouchMenu over the default settings page. For some reason though, it messes with my app´s own settings menu. As far as i know, TouchMenu just replaces the built in E.showMenu with some custom functions. My app does not use E.showMenu, but somehow parts of the TouchMenu are still drawn. Here is my settings code:

(function(back) {
	Bangle.setUI("");
	var settings = require('Storage').readJSON("contourclock.json", true) || {};
	if (settings.fontIndex==undefined) {
	  settings.fontIndex=0;
	  require('Storage').writeJSON("myapp.json", settings);
	}
  savedIndex=settings.fontIndex;
  setWatch(function() {          //save changes and return to settings menu
    require('Storage').writeJSON("contourclock.json", settings);
		g.clear();
    back();
  }, BTN, { repeat:false, edge:'falling' });
  Bangle.on('lock', function () { //discard changes and return to clock
    settings.fontIndex=savedIndex;
    require('Storage').writeJSON("contourclock.json", settings);
		g.clear();
    load();
  });
  Bangle.on('swipe', function (direction) {
		g.clearRect(0,24,g.getWidth()-1,137); 
		var fontName = require('contourclock').drawClock(settings.fontIndex+direction);
    if (fontName) {
			settings.fontIndex+=direction;
      g.clearRect(0,0,g.getWidth()-1,16);
			g.setFontAlign(0,-1).drawString(fontName,g.getWidth()/2,0);
		 }
  });
	g.reset();
	g.clear();
  g.setFont("6x8:2x2").setFontAlign(0,-1);
  g.drawString(require('contourclock').drawClock(settings.fontIndex),g.getWidth()/2,0);
  g.drawString("Swipe - change",g.getWidth()/2,g.getHeight()-36);
	g.drawString("BTN - save",g.getWidth()/2,g.getHeight()-18);
})
