Same app, different data.

Hi there, I have been using some different (IPA) versions of the same game (Hay Day) for multiple game accounts. However, yesterday, all of the versions seem to be using a same data. Which mean, when I logged in an account A on an app version 1, the app versions 2 will logged exactly that account A in by itself. I was trying to reinstall those IPA, factory reset my device, but the problem has been still there. Does anyone know how to fix it please? Thanks so much!
