Patch 5.14 Match History Bug

I recently had two games in ranked. Both of them had "Leagues Calculating" in the champion mastery system, and I thought I was lagging, so I decided to ignore it.

I checked my match history and at the very top was my Irelia game from yesterday.

What happened to my two matches? It seems like people are getting this error too ever since patch 5.14 I have seen a ton of reddit posts regarding this issue just posted today, or yesterday, at the time of update.
