HIghview POPLA - Warrington gym

I have had a rejection letter from Highview after submitting the standard template appeal from the NEWBIES thread.
They have not provided any evidence other than the 2 photos of the car entering and exiting the car park even though the appeal asked for all evidence including pictures of the signs in the car park, so can they rely on this in POPLA stage if they choose then to provide it?

I am currently writing my POPLA letter and have the relevant template points from the NEWBIES thread:

1. This Notice to Keeper (NTK) is not compliant with the Protection of Freedoms Act 2012 (POFA) due to the dates and the wording used.
2.The operator has not shown that the individual who it is pursuing is in fact the driver who may have been potentially liable for the charge
3. Highview Parking Ltd. lacks proprietary interest in the land and does not have the capacity to offer contracts or to bring a claim for trespassing
4. The signs in this car park are not prominent, clear or legible from all parking spaces and there is insufficient notice of the sum of the parking charge itself

Also, the signage at the front of the car park said 'For Gym Members Only' but did not specify a gym (there are 2 equidistant from my space) and allegedly used the 'wrong' gym to be able to validate parking. The terms and conditions weren't seen at all because they were car height (and so blocked by the parked cars there) and along the wall of the gym that wasn't walked past. Highview did not consider this mitigating circumstances in the rejection letter but is it worth adding to my POPLA letter?

I have pictures of the gyms relative to the parking space and of the signage but cant upload due to being new.
