Adding a new "Note" [Mandatory ] in the custom symbol which is already registered Library, the text of a placed custom symbol is initialized by Update the symbol.
Solution In the Custom Symbols, if we add or delete any Note, existing Custom Symbol Note gets overwritten, but modifying the Note there are no changes in the custom symbols.
User need to be add both "Arbitrary" as well as "Mandatory" Note initially while creating Custom Symbol and then modify the text as per the requirement.
the text of a placed custom symbol cant initialized by Update the symbol.
