Uhh, I Keep Getting A Message About Rank Decay?

So, i took a 4 day break from league and come back to a message saying that i have 7 days until my rank decays. I'm like, hmm I guess that's right, but I thought you had like 2 weeks or something in platinum elo? Meh whatever. So I start playing ranked games....

For the last 5 days, I still get a message warning me that my account is about to decay even though I'm playing a few games every day for the last 4-5 days. Today, it said I have 2 days left until I decay. Makes no sense!
