Those are called "expectations" and have nothing to do with Creo 
Creo is so literal that the method itself becomes exotic. And since those solution are not being worked out in software, you actually pay the $1500 annual maintenance fee so a much higher level process, the human customer support representative could help you understand how to make it work.
Yes, in fact, you can ask PTC why this isn't working as you expect, and you -should- get a reply as to why not and how it should function. It might take a while, and it might take some effort on your part, but in the end, there will be -one- answer.
one thing to remember is that Creo makes no assumptions. This is both good and bad. Only now, with Creo, there are some "hints" as to what you want in some features such as round terminations. You will have to give PTC some time to complete the ribbon protocol and actually start addressing usability.
I say much of this in jest, of course, but I have never known Pro|E to provide a guiding hand. All too often I find myself mimicking the action I want by doing the calculations for the machine.
For a simple (cough) exercise; build and constrain a scissor jack. It's doable... but if you can do it on the 1st go, you're an expert!
