Remap movement keys WASD for TAD

Hello. I have been playing vanilla and was able to remap movement from the arrows to WASD, no problem. I had to unmap all the keys that used those to do so, but it wasn't that big of a deal. Simple change.

However, I'm now loading up TAD and no matter what I do I can't get movement remapped to WASD. I have triple checked that I unmapped everything, even checked "allow conflicts" to be sure. Now my arrows dont worth but, inexplicably, S moves the camera down as intended. But no other key makes any movement occur.

​

Help.
