Board Game Arena

I have the Porter as a helper, which allows me to choose two different revenues when I pick a 2 or 6 die. However, it's not letting me choose two things. I've tried pressing on the card to see if that allows me to say I'm using it for this round but it's not letting me.

Is this a bug or is there something I'm missing?

After you choose the die (2 or 6), do your first action as normal. Then hit the anytime action button, and you should be able to touch the porter card and activate the second move.
