Are my chronocloth and transmute capacity SUPPOSED to be refilling every few days...?

I have an Alchemy/Tailoring alt. She's currently sitting at 63, and I log her on maybe a few times a week, mostly for profession stuff.

Since she's basically a profession mule, I specced her for transmutes and chronocloth crafting, because why not get a bit of gold per week? Most of the time, I log in after a day or two offline and she has 1-2 transmutes/bolts available to craft, which seems in line with the displayed cooldown of 16 hours and change. But a few times now, I'll log in and have 10 transmutes and 30 bolts, even though I definitely have not been offline for that long.

Are these *supposed* to refill once a week or something, or is it just still busted?
