Restoring WhatsApp names is not possible?

Hey recently bought the Huawei p40 lite.

Following problem:

I can't save anyone on WhatsApp, only add them to contacts, but they are all already added to the contacts (including their names). But somehow. Does NOT save it on WhatsApp… There's AGAIN this "add to contacts" (but they are already) or "block"… WHY?

Can someone help me please?

Is your contact list also released for WhatsApp?

PUUUHH how can you look it up

Go to Settings, Apps, All Apps, WhatsApp, Permissions. And see if everything is allowed

Thank you
