[Question] ThinnerBanners doesn't show the message content

So i installed ThinnerBanners tweak today, But i had trouble and it's whenever someone send me something i just see their name and three dots and i should just pull the notification down to see the content (faced this issue with twitter, didn't with whatsapp)

Here are some pictures so you get what I'm saying: https://imgur.com/a/vGYbR
