Refreshed Black Market Store already sold out?

So my Black Market store just refreshed with Gabriel and for some reason the Trait Reroll Tokens are already sold out. I haven’t purchased any of them since last week, and this was the first time popping into the store since the refresh so there is no way that I could’ve purchased them prior.
Do the reroll tokens have some sort of purchase cap? Or once they’re purchase from a hero they are sold out for good from that hero? What’s the point of giving me a wasted spot then?

It would be a bit odd if you haven't purchased them before, since this issue (as far as I've seen) happens when you've purchased the item from the same hero before.
