Unable to obtain cars escaped with from Lockdown mode

Hi, maybe there is a serious bug here:

first of all, I do jacked another player's b12th gtr35 before and still within 24h and I have obtained b 3rd gtr35. Then I unlocked and extract the b12th gtr35 normally and my contract show I do have obtained but I cannot find it in my obtained car list. Can you make it up for me.😃 

By the way, my offline story is still stuck in Sunday and cannot go forward!
