Powerup shows empty circle

Did TdZ stage 5 today and for the first two banners, after the roulette spin, I didn’t seem to get a powerup. Just saw a gray circle icon with nothing in it. And the companion app showed “No powerup”. Does that mean I got one of the Bonus point powerups (didn’t even know those existed until I Googled a minute ago)? On the third banner I got a featherweight.

You probably got an XP bonus, yes.
