That would be because the first 71 in the list is the most recent official English translation and then the 66-72 after that is fan translations. Probably even MTL
Ano so far is definitely there just for the misunderstanding. BUT I also cannot think of something worth more than him that would make them needing to go into the SS class dungeon again, which was pretty important to the plot.

I know it's hard translating another language and getting the meaning right, but that's just something I noticed
