Hi Tithi,
When sending an authentication command to key 9003 in SL1, to a MIFARE Plus X, I do get an answer with correct TI, RndA', PDcap2 and PCDcap2 from the card. If you don't see that in your log, I'd recommend you to take a look into your logging parser.
Then, I guess that your real problem is that despite authenticating correctly with key 9003, your card is still in SL1. MIFARE Plus X, enforces that changes of security level must be sequential, meaning SL0->SL1->SL2->SL3.
You cannot authenticate to key 9003 in SL1 and expect to change to SL3. You need to authenticate first to 9002, switch to SL2 and then once you're already in SL2, authenticate with 9003 and switch to SL3.
Hope this fixes your real issue.
