Notifications on Huawei P20 lite?

I've been running the Huawei p20 lite for a few days and still have one or two issues with my notifications

If my phone is locked and I get notifications, I can only see from which app but not by whom. I have set in the settings that the notification content should be displayed, however, is always only "notification content hidden" although I have not set it
If I receive notifications when my cell phone is locked and my phone then unlocks but does not open the notification, it will be gone the next time the phone is locked.

The best time to go to the store and get advice. This is relatively difficult.
