Since I already contacted ninja's support and they didn't know. I'd figure I throw this out to the community, and see if any one throws me a bone.
I haven't seen this error before maybe you guys can help shed some light on it. I get what it means, but I don't know what reason there would be not being able to cancel a limit not filled order.

I also already contacted MBT, but they seem to be ignoring me.
