IP Display Bug

I've been having a few issues with the store today, mostly just loading errors that can be fixed with a relog. However, after finishing a game I saw that I had 3170 IP so I went into the store to buy a new champion and the store thinks that I only have 3121 IP. I'm not sure which number is correct or if there's just a delay in the store recognizing earned IP. I've attached a screenshot and highlighted the IP disagreement, hope this is helpful!
