Character randomly emotes

im not sure exactly what is happening here, but it has to be a bug. while playing in any mode, my character will randomly do an equipped emote when i press an ability button.
i DO NOT have any emotes individually set to a keybind. just on the emote wheel i have to manually open and select from. this most often happens on mercy. and more often when i press rez, usually when standing still.

it happens enough to be noticeable and mildly frustrating in comp. but not enough to make the game unplayable like the moira in normalwatch bug.

i am on steam, playing with xbox controller and a logitech g502 hero mouse. i do not know how to add a photo or i would add one to prove no emotes are bound to my mouse buttons.
