Thank you for your answer.
I have migrated my flow to VX.1 and I was having this problem at new symbol design interface (xDx Designer). In this flow, the visibility checkbox does not appears for the Name.
I'm sorry that I forgot to add version info.
I thought there's a bug or setting that I need to enable.
For the quick solution I've created a new symbol with older version (7.9.5) and imported it to new library.
Can you clarify your statement about 'I was having this problem at new symbol design interface (xDx Designer). In this flow, the visibility checkbox does not appears for the Name.'
What do you mean by 'new symbol design interface'?
There was an app called SymbolEditor at 7.9.x flow, but with VX flow, symbols are opening for editing with xDx Designer.
The interface is little bit different than symbol editor, same with DxDesigner
Are you using the new embedded editor, available with xSD Systems Designer? If so, then this is a known issue with the editor in VX.1 and is in our plans to address as part of its development.
