Kivy USB Dual Keyboard Letters

I have a raspberry Pi 3 that launches an application using Kivy. There is a USB keyboard connected to enter text in the application. Each time I type a text box, the letters are duplicated. If I press and hold the key, the letter will also be double. Outside the application, the keyboard works fine (does not duplicate letters). It also works fine if I run the application on my PC. How to prevent double typing of the keyboard in the application?

An error occurred in the config.ini file for kivy. This file was in the .kivy folder.

Earlier in the input section, we had the following lines:

[input] mouse = mouse mtdev_%(name)s=probesysfs,provider=mtdev hid_%(name)s=probesysfs,provider=hidinput %(name)s=probesysfs,provider=hidinput

Removing the last line shown above resolved the double-entry error.
