Letters keyboard not appearing after phone restart huawei

[Android Central Question]

I have a password with letters and numbers to unlock the phone along with face unlock. Usually after restart you should enter the password to unlock, and I get the keyboard with letters and numbers. But suddenly I only get the number keypad, so I cannot enter my password to unlock my phone. I tried restarting several times, but I only get the number keypad. Its a huawei nova 2i
