Alexis V49 pads activating on their own

First off, novice here. Just got a V49 a few days ago as my first keyboard. I updated the firmware last night, and ever since, the pads seem to activate on their own. Well, honestly not entirely on their own, but when I press a key (or two or three) pads will light up. Has anyone seen anything like this? I've searched high and low but can't find any answers. Any help would be greatly appreciated!
