It's hard to say exactly how that happened without watching the steps you used...

But it kind of looks like you may be drawing in some separate curves for different surfaces rather than building them all off of a single shared curve framework.

There some other kinds of ways that could happen too though, like using a surfacing command that did not make use of some curves, like a one-rail sweep instead of two-rail sweep or network... possibly something like that anyway.
