Whenever I call my chocobo, the text in the chat log replaces what I suppose should be my name or "you" with a random other name, I've seen npc names, monster names and I'm not mistaken another character's name though I'm not sure about this one, I'll take a screenshot next time I log in.

It happens with both Legacy and Company chocobo in every area I've called my chocobo in so far.
