Some creatures don't have attribute icons

BlackSheep101

I cast Knightly Valor from Gideon's deck. It created the 2/2 Knight and boosted my 1st creature, but the Knight doesn't have an icon indicating it has Vigilance. I used Sharp Eyes to add Vigilance to the Knight, but no icon appeared. I'm assuming it has it, but because it's a token creature and not a card it's not displaying?

It's just a graphical glitch. After a few turns the icon should show up.
