> The central tenant of Protestantism is Sola Scripture

No, it's not. There were from very early on many different Protestant traditions, and sola scriptura isn't even part of all of them, much less the primary and universal foundation of Protestantism (Anglicans and Methodists, for instance, are Protestants, but have only ever held prima scriptura, not sola scriptura.)

> Protestants have a Bible that differs from Catholics/Orthodox - it excludes the Deuterocanonical books

Many mainline Protestants include the Deuterocanonical books in their Bibles, and in their lectionary, but give them lesser theological roles.

Anyhow, some Protestants hold to strict literalism as fundamental despite direct contradictions in the Bible. I think you misunderestimate the ability of people to maintain a religious tradition in the face of even flat logical contradictions in fundamental doctrine, much less a lack of clear justification for doctrine.
