Something is happening too quickly. Just to verify that is the case though, the way I'd handle is to add arbitrary wait stages between every single step of that part of the object's action, between every click, etc. I'd say most likely it'll work like that. If it does, remove one wait stage at a time until you identify which step is happening too quickly.
If you still have the issue, maybe take some screenshots and attach here so we can give specific suggestions.
