In a similar category, you'll notice the client name as Risa. There are a couple client order descriptions that list her as Lisa.
I'm not sure what version of her name they were intending to go with for NA, but I feel Lisa makes more sense than Risa! The Arks Layer JP translation had similar issues with names showing up differently in different parts of the game, especially for Yucreta/Eucrita/Euclita/Yuclyta. Some merch depicting her name in english does go with Risa though!
