Weird bar glitch on xerath support with xayah

So the other game some rakan autolocked even though I called support before him, so he fed top, but that's not the point. I had to play xerath support, but there were a bunch of glitches. First, my mana bar would often turn red and display "2/2" for a second(even when xayah was not there). Also, when I clicked tab to show everyone and their stuff, so basically there are 5 rows on each side, but they were all blank except for me, and all the text was messed up as if all the champions were piled onto the first slot(in the tab menu thing). I'm pretty sure it's not my computer's problem as I'm using MSI stealth with Nvidia 1060
