Send Email with Options Email Display issue

We are seeing a new issue using the Send Email with options that just started a couple of days ago.  We are formatting the body of the email using HTML.  In one of our flows that was created about a week ago when the email is sent the text displays as it should.  However on a similar flow we use the same formatting but when the email comes in it is unformatted and shows the html tagging.  You can view the orignal message and it is formatted correct, but not the new posting above it.  Is this a known bug or does anyone know if this can be fixed.  I have attached a screen shot.
