Question about the performance of Amazon Books

Hi, I have run GES-SASRec on Amazon books, however the testing performance is greatly lower than the Table 3 shows, as is HR@10: 0.4437, NDCG@10: 0.2727, MRR@10: 0.2201, while the table shows gives: HR@10 0.5405 NDCG@10 0.3553 MRR@10 0.2991.

Is there anything i have missed in the parameters setting?
