Bing Yi offered the River Map, which is indeed a genuine high-grade Innate Spiritual Treasure.
It's just that it has returned from the Acquired to the Innate.
In other words, there was a deity who replicated a "River Map" for fishing purposes.
To make it more realistic, it is highly likely that this deity took the replicated "River Map" into the primordial state for "aging" treatment, thus transforming it into a "high-grade Innate Spiritual Treasure."
This explains the concept of "refining a fake into a real" concerning the Spiritual Treasure.
Is it a high-grade Innate Spiritual Treasure? Yes!
Is it the River Map? Yes!
Is it the original River Map, born from the nurturing of heaven and earth? Absolutely not!
The powers might be equivalent, and the Great Dao it contains nearly identical, but there's definitely a hidden plan within this Spiritual Treasure.
Otherwise, why would someone go through the trouble to create an almost perfect replica?
