Well I'll jump in and try to at least advise. Be aware it's best to post technical questions in the appropriate section of the forum. If you are using iClone 7 use the Archive iC7 section
;)I have seen this issue from time to time in iC7. The dotted points, I believe, are keys created on the Path, that's normal. The avatar's, jumping off the path at the end, issue came about at some point in iC7's lifetime and was an issue for many myself included. When you Release the avatar from the Path you will have the jumping issue. I believe it has been corrected in iC8.
4u2ges posted a tutorial awhile back on how to correct the jumping of the avatar for folks. I couldn't get it to work for me but I'm sure I was doing something wrong. You might try to find it in his posts.
AS LONG AS THE AVATAR STAYS ATTACHED TO THE PATH...you're good. When the avatar is released from the Path it will fly back to it's starting point...not good!
