Remove help text from Replace when using Write with AI

Currently, when using Write with AI and using the “replace” function, all the help text is also copied into the email template.  This always needs to be erased.  Please provide help text outside of what is pasted into the email template.  In the screenshot below, the line break and anything below (Feel free to customize it further!) should not be inserted into the email template and is what I am referring to as help text.
