Acer Spin 5 uneven/broken keyboard backlight

Hi all,

I just bought an Acer Spin 5 (13") and I wonder whether it's normal to have an uneven backlight (especially the N key which seems to have no LED underneath it...).

Is it just me or everybody has that?

Here is a photo of the symptom:

Thanks in advance
