TBS 7.1 issue with Motion tool

I bought Tony Ross’ DVD and it is really great to learn TBS but I am having a problem with the Chapter 7 tutorials. I attached my object to a peg - and if I do not have my object at the center of the canvas there is an offset to the center of the motion trail. I’ve tried moving it but it won’t move. Has anyone run into this issue? https://100001.onl/ https://1921681254.mx/
Also, when I attach a peg to my object and animate the peg so I can see the motion trail, I wanted to change position midway through animation. So I positioned the timeline position marker to midway, clicked the motion trail button and moved the object up and the motion trail adjusted to a peak. I then went into the properties panel but no adjustment area is there. There is no Tension, Continuity, or Bias controls. I followed all of the steps and the first time it worked. Every time after that it has not. I have restarted TBS and my computer and nothing. I’m so frustrated. Does anyone know what I’m doing wrong or is it a bug? If it is a bug, will upgrading to v8 fix it?
