Cannot change language for some TV show / Comic

When I try to use Chinese - simplified as the metadata language for the comic Slam Dunk (TMDB link), it always uses English to fetch the metadata and never updates the metadata with Chinese - simplified. I tried other languages as well, but it always uses English. (To add more context, it works fine for other shows, only this show is kinda special.)

I’m using Infuse pro 7.6.4. I tried the app on multiple platforms (iPad, iPhone, Mac), they all don’t work for this show, so it seems like a backend issue.
