Using Valor points

Hi,
having obtained Valor points, I wanted to use them for one of my leaders. However, for most of my leaders (Drakkisath, Rend, Thaurissan, Baron, Sylvanas, Thanos, Sneed, Gromash and Charlga) the improvements do not appear when I click on “army improvement, Valor improvement”…
Is this a bug? Is it expected that these leaders have no room for improvement yet?

I noticed that too.

I wasn’t even sure how we could view/track our valor - is it by hero? If we see 3 options vs 1, does that mean we can get all 3 or just the 1?

I still have this issue, canot use valor at all
