I din't think it would necessarily be obvious to an enforcement officer, still less to a CCTV based system that two tickets were intended to be added together. Surely the PCN quotes time/date place and has some sort of infringement code. They usually send you pictures too.
Write to Parking Eye, per the provisions on the PCN and explain what you did and why.
If no joy follow appeals procedure and/or wait for them to take you to court.
