Cauldron Map Device MTX not working in Standard

I have Cauldron Map Device MTX and in standard it is no longer working. It shows "Cauldron Map Device (Keepers)" and all numbers (number of maps, scarabs, and other fragments used) are all zero. Was it reset by challenge league? I tried to remove it and place it back, but it is not working. I never played Keepers league.

How do I make it work and prevent it from being reset by new challenge league?
