Bumping in hopes of getting an answer.
I can't reproduce. My system opens D-R for the Tobit 13:13 reference (whether or not I have D-R prioritised).
I can't reproduce either. My system opens Luther 2017 (German language bible with the full canon) for Tobit and other deuterocanonical references according to the prioritization (it will open NIV for 66-books canon references as I currently have NIV prioritized above Luther). This would be fully what I expect of Logos: go with the prioritization, regardless whether and which resource is open or not.
