How do they function, rules-wise? Do they count down in rounds of combat, or are they "levels" of a feat? If they're automatically adjusted somehow, they may require API, which is a Pro benefit. But if they're static markers, they should come with the starter set. If they don't, they really shouldn't be in the screenshot. Even if they do have some API-enabled functions, they should still be usable with a free account, you'd just have to adjust the number manually. If something from the marketplace won't work without a paid sub, and doesn't say so, you'd absolutely be entitled to a refund. I don't know anything about the game, but it looks like they're not stuck to the tokens like actual token markers. They seem to be in slightly different positions on each one, so I think they might have been hand-placed on top of the relevant markers? Someone who owns the content may know.
