The documentation states theses reasons

Refund amount exceeds payment amount or
Partial refund for non-cleared transaction.

Which is these issues causes this? And what should I do about it?

The scenario I'm trying to verify is to create an order payment and hold an amount, then later capture either the full amount of the order payment or part of it.
