Use the namespace for non-user-specific queries

What causes this issue?

Query names must begin with the following characters:
Non-user-specific query names must begin with a slash (/).
User-specific query names must begin with a letter.

System Response

The system checks only the first character in the query name.
The system automatically inserts a slash (/) as the first letter in the
query name.

How to fix this error?

To create a user-specific query instead of a non-user-specific query:
Delete the slash (/).
Enter a letter (A-Z) as the first character.
Set the <ZK>User-Specific</> indicator.
