Sub-Contractor's Proposals

In an unamended JCT D&B Sub-Contract, if there are Sub-Contractor’s Designed Works but the sub-contractor has not submitted any Sub-Contractor’s Proposals (i.e. his offer matches the Contractor’s Requirements), should all references to the Sub-Contractor’s Proposals be deleted from the Agreement and the Conditons?

In theory yes. You would be best advised to submit your proposals for the CDP elements so you clarify the extent of your design obligations.
