Additional headers not working

There is an annoying bug.
Regardless what I put into the Additional Headers Fields.
e.g. Cc:[email] where the field email is required and therefore it couldn’t be empty
the field is always marked as incorrect.
This is the message I’ve got:
The Cc field value is invalid. How to correct this?

But I also want to send the Email to the filler of the form.

I have tried to set it into the to-Field but this was also marked.

Hopefully this bug could be solved asap.
