1. Signature error: When both parties sign paper contracts and electronic contracts, it may be due to negligence or other reasons. In this case, both parties should re-sign the paper contract and the electronic contract to ensure that the signatures are consistent.
2. Version difference: Shell Platform may update the contract version during the contract signing process, resulting in differences in the contents of paper contracts and electronic contracts. In this case, it is suggested that both parties contact the customer service or relevant staff of Shell Platform to obtain the latest version of the contract and re-sign.
In either case, both parties should ensure that the contract signing process is legal and effective, and avoid unnecessary disputes. If in doubt, it is recommended to consult a legal professional or lawyer.
