[BUG] Names with Chinese Symbols are multiple times shown

[cd-FileX]

I added chinese symbols to the beginning of some contact names and if I add them ~to the favorite list~, they are added multiple times in different variations

Works normal as it should without them.

Version: 6.19.1 Pro Android: 10 (Not rooted or customized)

EDIT Each one of those is one for every messenger app plus the original. The only one that should exist and include all others should be the one with the symbol as first character

Second edit

This not only happens in Favorite contacts, it's the same thing everywhere

EDIT 3 WhatsApp and Signal are now merged but still separated from the original contact
