How to remove control point in SubD

Hello Peoples,

I created this SubD model and failed to remove a control point on a crease.

This model is converted from a polysurface, and I was trying to merge the two creases into one.

(The chosen point is the control point)

(When I dragged the control point, the triangular face transform into other shape)

Can someone give me a advise?

Thanks for helping.

Hi, thanks for replying
Somehow my control point can not be deleted.
Could you please tell me how to do it?
