Question:

Why does the Vault sharing rule API name remain the same but sometimes it is increased by 1, such as product1__c?

Answer:

• To keep the sharing rule API name unique, Vault auto-increments by 1 when the same name is created in the same place.
  
  Example: When creating two sharing rules with same label and name under one role, then Vault creates the second name with an extra number.
  
  
• If a user creates the sharing rules for two different roles, then the name is the same without an extra number.
