I added some randoms people on Festival Plaza that were over Lv 100 in Festival Plaza level last night to my VIP list to do the FC trick.

Today, went I went to look at their profiles and for some reason, I can no longer see their Festival Plaza level. When I further investigate their profile and look at it, it just shows -.

Is there a reason for this? Will it affect my ability to do the FC trick with those that I can't see their FesLevel?
