Search not visible on mobile

Hi. Just found your plugin, and it was exactly what I was searching for. I need a freestanding search field only on mobile.
I have followed your instructions, but I can´t get it to work. We use also another company for more advanced Search that have installed their solution recently. And we use another plugin for menu/search on mobiles. I don´t know if there is a conflict, but now only the standard menu/search and the plug in one is visible, as before. Ajax Search is not enabled. Can you help me?
I show my settings on the images attached.
