Trade offers (ARAM) NOT appearing.

The sound will still play. But sometimes I hear the ping so I decide to check who is trading me. But all the trade icons disappear and nothing appears on the side to accept or decline, or who even traded with me! It tells me who declined the offer when they cancel it. But I thought I'd let you guys know since its not something that happens often but I do encounter it every now and again.
