Weird Oreo notification problem

[Chicken4K]

Okay so this is really weird and I don't know how to describe it but I will try my best
I really enjoy Oreo but there is a strange problem with the notifications that I have, so I thought maybe I'm not the only one
It goes like this: for example whatsapp, but it happens in all apps as far as I have noticed
if a person X sends me a message, I get a normal heads up notification
but when another person Y sends me a message, a heads up notification will pop up, but it will show the contents of the person X
if another person Z sends me a message, I will still get a heads up notification from the first person X
Does anyone else here have the same problem? Could someone help me solve it because it's really annoying and I miss important notifications constantly...
Thanks
EDIT: Already tried wiping the phone... didn't help unfortunately
Also notification dots don't seem to work for me, like mentioned in the other thread

That's a whatsapp bug probably caused by a poor code refactoring/update to the new oreo notificaiton fw. Stop reflashing your phone and wait for a whatsapp update. (which previously had so many bugs with the notifications).

**And notification dots are not implemented yet. It's also missing from the xperia home beta. More features will hopefully come in following sony updates... Stressing on the hopefully part lol...

This happens with WhatsApp and Signal, that I noticed. It doesn't really annoy me tho, to be honest. I could just slide the notification panel down and read the old notifications

Then it's not only WhatsApp that has the bug.
Guess we have to wait for all the apps to be updated...bummer
EDIT: I think this has something to do with Sony, because my friend that uses a OP3 doesn't have this problem.
