Credit to Morgause for finding it

but ultimately I found the "AutoRunSettings.sav" file, deleted it, and then rejoined the server I was playing on - this reset the keybinds and buff display to default.
The file can be found in "steamapps\common\ARK\ShooterGame\Saved\SaveGames"

PS. sorry for the necro but this was the first place i came when i had that issue hope it finds others well
