Thanks for your answer.
I am using Unreal Engine 5.3. So when I type splash in “all settings” only a few banners appear. There is no other setting here.
However, yes, I am using level streaming.
I also tried disabling the add-ons. It didn’t work. If I could find the thing those three dots belong to, that would actually solve the problem. It appears in Standalone Game mode, by the way. I said it doesn’t appear in the title, but I saw it appear.
