It appears your Kindle software is glitched. Try performing a power reset by holding the power button/switch for 20 seconds. Your device will shut off then turn back on allow up to 3 minutes for the software to load up.
Please let me know the outcome of the solution. If it does not work we can continue troubleshooting.
