Points disappearing in Arenas

I’ve noticed multiple times that points disappear without me losing a game. For example, I’ll play arena 17 for a while and wind up with 4167 points. I’ll quit. Then when i come back later in the day, i suddenly only have 4157 points. I’m assuming this is a bug. Can it be fixed? What about the points i’m Losing and how do i get them back?

P.S. Happening to many other players as well.

Currently, the very top arena does not refresh the medal count until you close & open

When you log out for a extended period from one day to the next many of us are loosing points in the 17 arena.
