Please look again at your own screenshot:
I marked the original release date there for you because you missed it (blue line). Please don’t look at original release dates while talking about release dates.
Sadly, with Roon v1.8 the display of the various release dates has become a mess. For albums without original release date, the release date is shown in the place at top while, if both are present, the original release date is shown at that same place. In album lists, the same date at top of the album detail page is displayed – without label to tell which one it is. You can therefore not use the date displayed in album list views to determine the correctness of the sorting if you changed the sorting (
Settings|General > Album dates for sorting) to use release date instead of original release date.
