2 Perk Apps showing different points?

So I got Perk Scratch very recently, played it for a bit, then downloaded Perk TV and Perk Wallet. But, my Perk TV app shows 1018 points while my other 2 Perk apps shows 968 points. (And I tested it with the scratch cards, all 3 do update the +2 or whatever I get.) I don't know if this should be considered a problem or not, or what I should do about it. Just curious if anyone else has seen this issue and what they did.
