The bio ik problem with my industrial robot

[h8476532]

I used the bio ik to set up my industrial robot for the inverse kinematics, but I face some problems, I have already asked the publisher but still didn't receive any reply.
I already follow the readme file in the package, but still can't figure out how to solve it.
And I have already checked the demo model to see how the publisher set up the model, but still does not work, as the pic is shown below I set up the target to drag it to let the end effort can move, but you can see my robot becomes weird.

Best,

Tony
