Date of contravention - 13 June
CC issued - 28 July.
The CC was issued in July, 28 days or so after the PCN.
The photos suggest the PCN was issued by post because the driver either drove away or prevented service. Your opening post made no reference to this. I suggest you get back to the driver and post all relevant issues.
The PCN was issued because the car was parked on DYL where loading restrictions were in effect. Nothing to do with loading bays.
