Was looking at a build using Starviper Guri and the card says "At the start of the Engagement Phase, if there is at least 1 enemy ship at range 0–1, you may gain 1 focus token.". I assume it means "Calculate token" but not played Version 2 yet and properly read the rules so might be able to use both tokens but no idea how :)

It's not a bug, Guri's ability gives her a focus token, even though she has Calculate on her action bar.

Oh that's handy
