I don't understand how the Shorter Schedule of Cost Components (SSoCC) wasn't included as it's automatically included in the conditions of contract when main Options A to E are used.
In order for it to be excluded it would have required a Z clause to omit it? The amendment of clause 63.13 is irrelevant in this instance as the PM isn't trying to argue that you should have used the BoQ.
Assuming the SSoCC has been correctly omitted you need to analyse how the contract intended the adjusted CECA rates to be used. If it's not clear then you may have an ambiguity and / or inconsistency which should be notified under clause 17.1 and resolved by the PM by instruction. If this instruction changes the Works Information then it would lead to a compensation event, however it it changes other contract documents then it won't.
