This is Apple's work - they show all enabled purchases/subscriptions author have enabled for price testing. And once you add one, removing it would mean the user's subscriptions auto-renew would get canceled, so they stay and accumulate.

And there is no way for the app to mark "this is the current pricing".

The Pedometer functionality is free, and I’ve been using it for many years just because its display is pleasant.

The map tracking features cost $29.95 a year.
