Confusion with signal not updating the dom

I am not sure what to make of this other than the fact that I am confused, but the filename() signal doesn't update the dom whatsoever. Even though the createEffect is working fine and outputs the correct state of the filename signal. In my simplified example updating the signal doesn't update the dom but only when removing the filename after an initial filename value is passed, but still it wont update after inserting a new file. I uploaded the file as an image and the actual file, if you want to take a look and help me out. Because it's a bit bigger than the allowed non-subscription text length * cries in poor *.
