Welcome to Android Central! Do you have an exact model number? It's always hard to tell with these lesser-known brands, but it may be that that's what the manufacturer intended. Or it might just be a hardware glitch.
Is there a reason why you're powering the device down? Unless you're not going to use an Android device for an extended period of time, powering it down is usually unnecessary. Just use it during the day, and charge it overnight if it's needed.
