The Runner Bunny Profile Picture says "Use 3 boosters at once for a total of 14 days"

Can anyone clarify what that means or what to do?(or what you did when you got it)

I just used 3 boosters all at once, "See The Light"(for free as it was won), Generous Customer, and Popular Passion. But, it still only says 0/14 days. If it because the See The Light booster was free and not using the gems??

I can't find anything clear on what to do, and I don't want to waste a ton of gems tinkering with it. Thanks!
