How to get back subprocess symbol

[Michel777]

Placing an edge-aligned event on a subprocess removes the symbol  ( "+"), but the Type remains subProcess. How to get back the symbol?

There is a subprocess SUBP1
The Typeof SUBP1 = subProces
The symbol  "+" is displayed

Now I create an edge-aligned even on the SUBP1
The Typeof SUBP1 = subProces
The symbol  "+" is disappeared

Right-click the sub-process and untick the "Is Expanded" command.
