We could change the names to TL1-Basic, TL2-Member, TL3-Regular, and TL4-Leader. Then the alphabetical order would always be the same as the trust level order. (I would also find it helpful on the user cards, as it would make it easier to see the TL without knowing the ‘name’ in the current language.)
But the trust level badges are not the only ones in the wrong order:
In German, for example, the badge for 150 solutions is also shown before the one for 50.
And I think the other topics about the order of the Posting badges also address the same issue: alphabetical order doesn’t always feel logical.
