Unable to use xpath properly with Appium Helper

#### What are you trying to achieve?
Click on a app object when using xpath to select the second element with the same text

#### What do you get instead?
When I use I.click('//*[@text="6º ano"]') it works
As I have several elements with the same text on the screen and I woul like to click on the second
I.click('(//*[@text="6º ano"])[2]') is not able to find any element

> Provide console output if related. Use `--verbose` mode for more details.

```bash
Emitted | step.passed (I wait for visible "(//*[@resource-id="...
Emitted | step.finish (I wait for visible "(//*[@resource-id="...
Emitted | step.start (I click "(//*[@text="6º ano"])[2]")

### Details

* CodeceptJS version:v1.4.5
* NodeJS Version:v8.11.4
* Operating System:Windows 7
* Appium: 1.9.1

When using the appiun session to inspect. it is able to locate the object
When playing the script even making sure the page is fully loaded script is not able to locate the second instance of the object.
For this instance
I.waitForVisible('(//*[@text="Ciências"]/../..//android.widget.TextView)[2]',10);
Script is able to detect the instance
When clicking, it cant be detected

Comienza con el manejo de I.click en Appium Helper y compáralo con la ruta funcional de I.waitForVisible. Reproduce el XPath con texto duplicado en las versiones indicadas de CodeceptJS, NodeJS y Appium, y verifica después que hacer clic en el segundo elemento coincidente tenga éxito sin cambiar el comportamiento existente para un solo elemento.
