This should create a centered window but it's not

Hello

I created a blueprint that should create a centered window no matter where like the editor or standalone game. It’s not and I’m not sure why. I tried changing the size to desired size and also the alignment and center point to 0.5 from 0.0. Maybe someone has a example of a centered window in the screen or know what the problem is.

Any help is appreciated.
