My Marauder can't move after initiating combat

[Mopti]

Newb question. I've been playing a summoner and decided to try Marauder. Only with the Marauder, every time I initiate combat my character locks onto the target and I can't move until the mob is dead. Moving with the mouse doesn't work nor does movement with WASD. This movement problem does not happen with my Summoner. Thanks in advance.

It will toggle the target lock off, a seemingly pointless and annoying feature.

It has legitimate accessibility use cases and is easy enough to turn off for those who don't want to use it.
