Interpretation setting error

Previously person A was an English interpreter.

But I created even a new link, and I didn't appoint her as an interpreter.

But Zoom automatically made her an Eng interpreter. I didn't set an interpreter when I make the link. 

Zoom remembered previous interpreters, and they just made them interpreters.

But there's no list of interpreters, I can't remove the interpreter setting from her.

How can I solve?
