Delay Freeze Post-Fader Issue

Hey Guys,
While I'm loving the addition of post-fader fx in Traktor, I've run into one issue. If I initiate and echo freeze [params as such– D/W:100% ,66 ,100%, 4/4] it seems to go on literally forever. I'm not familiar with this, and it could be completely normal, but here's my issue: I CAN'T GET IT TO STOP. Is this a bug? Is there some way to stop the feedback?

If it matters, I'm using an S4. If I turn off the controller and turn it back on, the echo is gone.

Thanks dudes and dudettes!

Turn down the feedback a little and it will fade.
