Backspace function on keyboard is sometimes not working

The backspace function sometimes doesn't work when I try to make a new world. Sometimes I had to type things in and then delete them just to delete the "New World" part.

To get to this step do the following:
1. Click "New" on the World Selection screen.
2. Click the world name to edit it.
3. Try doing backspace on it and it will not work.

Sidenote: This bug started to occur when I updated Google Keyboard.

Extra Details:
Happened on Android 4.3 when I updated Google Keyboard.
Upgraded to Android 4.4 and the problem still occurs.
