Has anyone noticed this? It has happened on an android and an iOS. I noticed it a few months ago.

Happens to all champions as part of game design. The champ may be a higher rank, but they're also a lower level. In part it is incentive to level the champions up, but there's other reasons for it that I just don't remember.
