The problem in these dialogues is that the word "sola" isn't employed with a consistent meaning by Protestants.
As to Scripture, the usual explanation is that Scripture is the first and highest source of truth; that other sources are not thereby precluded, just that ultimately Scripture is the measure. So here a more accurate shorthand expression would be prima Scriptura. "Sola" here doesn't strictly mean "only" or "exclusive," but more like "principal" or "primary."
But when the discussion turns to soteriology ("sola fide") Protestants are very clear that "sola" does mean "only" or "exclusive," assuring me that "works" have nothing whatsoever to do with our justification.
So if Protestants would use "sola" consistently (which they don't), there might be less confusion on the Catholic side.
No, the problem is that Catholics won't listen to what Prots tell them sola means.
RC's keep fabricating what they wish it meant so they can shoot non-Catholics down with it, but strawmen are strawmen and while it may make RC's feel good, they are accomplishing nothing other than demonstrating to the world that they will not listen to others.
