Framework three profile connection

Hi guys,

I am trying to start using the framework extension with Creo 7. 
I am building a simple frame where there are 4 profiles connected together for the frame's top and 4 legs connected at corners.

I am able to do joints for the top but when I try to connect the top with legs I get error message asking me Overwrite existing join? No matter what I do I am unable to connect this profile with existing joint to another profile to the leg.

I watched some YT videos and there presenters are able to do what I want. What could I be doing wrong?

Thank you.
