You will need to check whether all your objects are activated correctly as well as the cache is up-to-date/refreshed.
Just to double check the post mapping result during runtime, can you add an AM logging step in the ICO and check the payload after mapping. Check if that payload is having ZSD_PGI or ZSD_PGI_HEADER. If it is ZSD_PGI, then maybe your objects/caches are incorrect so the mapping is generating incorrect payload during runtime.
