Strange behavious of "CLONE" incident

Hello.

I have a function to clone incidents in HPSM.

So I have new incydent, I'm pressing "Duplicate",

It coppies all record,

I pressed save and I have all record greydout - not possible to edit it.

I need to Close the window and open the inc again, then I have everything editable.

 

What is going on ?

Any advice please ?

Dom.
