Unable to rebind UI Menu Movement Keys. Ruins the game for ESDF players on M+KB

Like the title says, I am an ESDF player and every time I die in a match if I happen to hit E(which is my forward petal button), it cycles my class to another class. So in the heat of the moment I will be pushing forward, click a new place to spawn, then spawn in as a different class. So I have to purposefully die in order to change my class back to what I was using. This is incredibly frustrating and the UI movement keys are locked to WSAD and Q and E are hard bound to menu left and right cycle(similar to what the top bumpers do on controller). There is nowhere in any configs I've found that show menu UI button options either on top of it being almost impossible to decipher. Please fix this ASAP!!
