To quote a user report:
Pressing W+S on the keyboard moves forward. It should have zero movement.
Pressing A+D on the keyboard moves right. It should have zero movement.
The proposed fix for this is to make different input actions for Move Forward, Move backwards, etc
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-176016 in the post.
