Why did it happened?

So, today I completed the Legend Tier (Highest Tier in puzzles) and after completing it, I got reset to Wood Tier (Lowest Tier) in puzzle. Does anybody know why did it happened?

Here's the proof by the way:

nice

Thanks! But please let me know if it's normal that we get reset to Wood Tier after completing the Legend Tier in puzzles.

It is, on the lederboard whith your friends you will be shown first with you starting on wood the second time
