Huawei P20 lite swipe left or right through the cover?

Yesterday I got the Huawei P20 lite, but today I'm always shown on the lock screen "swipe left or right through the covers". How can I remove this?

Not at all. Unlocking can't be deactivated here

It is also displayed in the notification bar and yesterday I had the problem not yet.

You have to restart the phone. If that does not work, try pressing the "Volume up" key and the "Unlock key" at the same time for about 30 seconds (when the phone is off). First comes the sign of Huawei, but you still have to hold down, then comes EMUI (let go). Since you have to press the bottom of the selection and wait until he is once gerödelt by (with me that was very fast). Then reboot (the top choice). Then he starts again and it was gone with me. Otherwise, call the Huawei customer service, which helped me a lot. I had the same problem.
