Black Blood - S1-E1
Other mistake: All the Greek name variants are used over the Latin ones - including even "Odysseus" over the more familiar "Ulysses" (who is the same person). However when the story of Actaeon comes up, it's suddenly the goddess "Diana" that he saw. But all the gods have their Greek names, so that should be "Artemis." (As indeed is used in episode 2).

Episode #1.5 - S1-E5
Other mistake: When the women are practicing their archery skills, one of the women says "I wonder why Lady Yun is absent today." But the captions add an extra N to the name Yun, misspelling the name as Lady Yunn. (00:15:41)
