The Dude builtin tool - (copy) duplicate - I can't delete

Hi

in “The Dude” tools, for testing I copied the built-in tool.
it’s very bad.
The “built-in tool” / “embedded tool” flag was also copied.

Please, help me.
How can I remove the “built-in tool” / “embedded tool” flag
or
How can I delete a new copied tool with the “built-in tool” / “embedded tool” flag

best regards
Piotr
