[Plugin: Polylang] Language switch don't disappear

Hello everyone and thanks in advance for your help.

I installed Polylang to translate my page.
When finished installing and adding a new language has appeared a switch to choose language in the header of the page.

I do not like this switch and the problem is that I find no option to make it disappear.
I can add a switch in the main menu, and customize it as I want, but the original switch does not disappear in any way.

Is there something I’m missing? Somebody can help me?

I attached an image to better explain the problem.

Thank you very much!
