Multiple Request Samples issue

Thank you for the good tool for API designs.

Do you happen to have a known issue about generating request examples?(x-examples)
When I added an example to a request object, another new in: body object will be added to the ymal files and shows me an error.

error : "parameters property uniqueItems should NOT have duplicate items (items ## 2 and 3 are identical)"

Because the new in: body object has also a same example object.
So I deleted the second example for testing but the second example object still exists in the codes(yaml files).

I need to editing manually every time.
Do you have any idea?

Thank you.
