ive tested it here on 2 player, and i can confirm this... i cant test every letters, but i dont get any fake logo with letter "D" too

i think its fixable by Magic-Mike

To add to this, if it starts with a number it doesn't show either, i have tested every letter and it seems only numbers and "D" that doesn't show anything.
also not sure if anyone already mentioned it but accented letters show as squares.

edit: not every accented letter shows as a square seems to depend on the font.
