What happens if both parties present evidence supporting their conflicting claims regarding the subject matter of the sale?

Primary text
If each party presents valid evidence supporting their respective claim (e.g., one proving the sale of the slave and the other proving the sale of the female slave), both contracts are established because the claims are not mutually exclusive. This is similar to a situation where one party claims a sale of both items and the other denies it.
Supporting text
If only one party presents evidence supporting their claim while the other does not, the contract corresponding to the claim supported by evidence is established, and the claim without evidence is not.
