The dub problem is a Crunchyroll problem, in my experience, having been a Crunchyroll member before the merger. Dubs on Crunchyroll where a complete mess, each time they tried to fix it, it got worse. As you mentioned, dubs being displayed as seasons.
After the funimation buy out, I see dubbed titles being fixed, and more dub options being added.
