Part of contract law is that the legal standard for enforceability is "reasonableness"[1]. If there is a clause in a contract that you want to exercise, but your counterparty claims they didn't understand it or intend it they can take you to court. Unless you can convince a judge that they might, at one time, have wanted to agree to the contract then the contract is not a basis for you to take that action.

Contracts have always had a healthy dose of manual debugging that have allowed them to function.

[1] The idea of "a reasonable person" is used heavily in the US legal system and has problems but it also has upsides.
