Fail to generate Curve/Curve intersection (CCX) please help

Hello guys!
It is weird that I could not get all intersections from curve groups C2 and C3. I have checked the curve in both groups were PLANAR, however as you can see only 7 intersections points were generated.
How could I solve this problem of lacking intersections?
Please give me some advice or suggestions.

Thank you!
Ely

Oh! Kim.
Thank you so much!
That’s what I want!

I still have one question: Why I have to Shift Paths after CCX to get what I want?
