[GAMEPLAY] Minor Bug: 5 Spoils of War lights instead of 4

Playing ARAM like normal and have Face of the Mountain, and I notice there are 5 hovering lights surrounding me instead of the usual 4. The buff bar still showed 4 stacks, and after using a stack it went to 3 lights and everything was fine after that.

Left picture shows the 5 lights, right picture shows everything is back to normal later that game.

I don't remember what other items I had at the time, but my final build was: Iceborn Gauntlet, Mercury's Treads, Face of the Mountain, and Locket of the Iron Solari.
