I am running version 3.0.4.
For the 2015 show “Heroes Reborn”, on my details screen, the app shows a progress bar for Specials that says 6/9 episodes, and the orange bar matches that. However, all 9 Specials episodes are checked as watched. I also looked at the details for each of the episodes and selected the 4-line option at the bottom of the screen. Every one has the watched indicator checked and highlighted in green and includes a watched date.
