What Artist Fields are Used

Some of my albums seem to have two Artist lines. Below is the Album info for one where you can see both Dan Hicks and Dan Hicks & His Hot Licks displayed.

If I look at the fields associated with the album I see Album Artist is Dan Hicks but I see no Artist.

If I look at the tags in J River I see that both Album Artist and Artist are set to Dan Hicks.

I have manually set preferences for every album to be to use file tags and not Roon data but something seems to be not working as in Roon I now see two artists Dan Hicks and Dan Hicks & The Hot Licks.
Does anyone have a solution to propose since I have already specified the file tag preference and rebuilt the database?
