Teletoon is outside the scope of the wiki. IIRC, DC Universe had this typo as well, but it was corrected. I'd have to check.
The Closed-Captioning is not, and never has been, official. It's just a third party job that is never verified or carefully vetted. Therefore, it's not a goof in the episode itself. Only hardcoded captions used for non-English are relevant for that.
YJ didn't have a good CC in s1 and 2, and 3 is even worse, from what I've heard. There are probably tumblr or reddit threads full of bad CC.
