I am Platinum 5 in Soraka's Vigilantes and, i have realized that when I logged in into the alpha/beta client, it gives me a notification saying I am in risk of LP decay after 4 days though the season has pretty much ended and I have received my rewards. Hope this issue gets fixed.

This is simply a display bug, since it's the preseason and you're unable to play Solo/Duo queue until it launches later down the road. This will not affect your LP or ranked standing.
Let me know if you have any questions.
I'm getting the same issue as well. I dunno why they didn't turn off LP decay yet. I did find a red in one person's comment asking the same question and its a display bug here the link and you can read what he says. I also reported the bug to them as well and borrowed your link to show them hope you don't mind.
