Unfortunately most subbers these days work from scripts and don't even watch the episodes.
The closest thing to a connection to the title in the dialogue was Ruri's "it's like we're in space", so it's no wonder they missed it.
The English guy even forcefully inserted his fake title where it shouldn't be. (she said 秘境 which means an unexplored secluded area, not "lost planet")
