Pilfering ring data when league ends

The pilfering ring is currently tracking data in Affliction league. When I tried to equip the mtx to my character in Ziz's gauntlet it warned me that all data would be deleted.

When affliction league ends, does the ring maintain the historical data for affliction league or will it be reset to 0 and set to standard?

This changes how many rings I purchase: If it keeps the historical information then I could get a ring for each league to maintain all data, or if the data is lost, I will need to make sure to screenshot it before it ends.

Same doubt here, hope someone at GGG's know whats going to happen with them
