I suspect the judge is giving you the opportunity to change [should your wish] anything in your initial defence now that the claimant has played their hand.
it doesn't say witness statement but formal defence.
the defence you filed:
I (NAME) am the defendant in this matter and at the time of the alleged violation was the registered keeper of vehicle CAR REG. The claimant has failed to prove keeper liability and I deny any liability for the entirety of the claim.
The claimant has ignored the defendant's CPR request. They have failed to produce a contract with the landowner that assigns them the right to enter into contracts with the public and to make civil claims in their own name, so the defendant does not believe that the claimant has locus standi in this matter.
The defendant also believes that no planning consent was obtained for the current signage installed in 2018 as required under the Town and Country Planning Act 2007. This means the signage is there illegally and it is not possible to enter into a criminal compact.
In any case there was no contract between the claimant and the defendant so no cause for action.
