What I have tried to resolve the issue:
-restart DayZ and reconnect to the server
-restart my computer
-double tap all keys that are related to movement
-unbind "strafe left"
-bind "strafe left" to a different key
-reset "strafe left" to default
-reset controls to the DayZ profile
-connect to a different server on a different part of the hive, new character still keeps walking left
-reverted back to stable and joined a server, no problems here, patched back to experimental and the problem occurs again
