It's a accolade award and listed under your passive traits. There seems to be a "bug" where they will show up on your power bar, happens to me mostly on the ground and never more than one at a time.
I've had this occur with the Efficient Officer passive trait from my Liberated Borg BO. It was there until the next patch, then it was gone. I couldn't do anything with it, though; it was just the normal passive trait.

it sounds like the accolade bonus of +2 health points space is showing visually. I though they were suposed ot stay hidden by design?
You can't activate it it's a passive trait.
It is a passive ability given by an accolade. There is a bug that causes some passives to appear on your power tray. Simply drag it off.
Will remember that.
