There might be something about chors and actions in the tech reference......which you can probably get a link for by searching the forum. And as I say that, most of the problems have come up before in this forum, so this is possibly the best reference.
Regarding your explanation, to be honest, it's hard to follow these issues with words. Your best bet at getting it solved is to provide screenshots outlining clearly where the problem is.....including the timeline/properties etc. Or if you can provide the proj file even better.
