The role of confessor and that of spiritual director are very different.
A confessor deals with the sins and makes suggestions for overcoming them in the future.
A spiritual director listens to your spiritual journey, helps you to understand it better, offers suggestions and directions on how to enrich it further.
One person can fill both roles, but it is not necessary.
In the case, where you are getting conflicting advice about a particular sin, bring it up, say X told me to do this about you, now you tell me to do this. How can I do both? Get the confessor and/or spiritual director to understand what to others recommended and work from there.
If you are using multiple spiritual directors, you need to choose one as primary and let each spiritual director know about the others. It will help them in assisting you.
