Favorite title issues on 3DS

basically I can’t see many of my friends’ fave titles due to some weird issue. on one of my friends, i got the data for the title when i streetpassed him with relay in streetpass mii plaza, which added the title data to my system’s database of software it knows about. and this issue is affecting my other friends as well. in fact, my fave title, Animal Crossing: New Leaf, didn’t load on @ibutoru’s 3DS friend list. does anyone know the cause of this? 3ds should normally know about every official software from every region if it’s been connected to the internet on nintendo network. and i’ve had my system for 3 years, although the data was transferred from a system i got 4 years ago. Idk why I transferred from New 3DS XL to New 2DS XL after just 8 months. And I’ve been using the 2DS XL for 3 years without going back.
