The Masoretic Bibles

Papalism is not Papalism for two key reasons. Just because a pope claims something in a letter, it doesn't mean that therefore the entire church accepts that. If this was a papal situation, there would not have been a council. They would have just looked to the prior condemnation of monotheletism by Pope Martin. It's no different than saying divinity can be a generic descriptor or of a God of a demon or of the true God. People make dumb theological mistakes and errors about things like this.
