> When experiments are launched there are two records in EXPERIMENT SUMMARY table for LAUNCHED and EXECUTING state which has the exact same state change time. In PGA however two records show up for the same experiment and with same status. e.g.: two exact records for a single experiment. This only appears until the experiment is FAILED or COMPLETED. But both users and gateway admins notices this and this needs fixing.
