Duplicate Composers/Lyricists in Classical Lieder

A question to all those (@SwissChris, @joel, @bbrip, @Tony_Casey) who experience duplicated “lyricists”:
What is your Import setting for “Tracks Production Credits”? Roon, File or Merge?
(I already know that Tony’s setting is “Roon”)
I have a suspicion that the poets shown as extra composers have their origin in the “Text” credit which belongs to the “Production” category of the Roon Credit Roles (https://kb.roonlabs.com/Roon_Credit_Roles)

This post explains a bit more in detail what I have found out so far.

My own Import setting for “Tracks Production Credits” has until now always been “Roon” and I haven’t tried any other setting. But maybe, just maybe, setting this preference to “File” would eradicate the duplicates problem (and most likely create others…)
Perhaps something to try out? I’ll keep you posted.
