Last seasons rank not displaying ?

Last season (season 9) I got placed in Gold IV, note that this is before preseason, and I received some of the rewards, but not all of them (considering I was honor level 0). Now that season 10 has begun, i wanted to check if i have "Last seasons rank" displayed like I hit gold, instead I was to find that slot to be empty, I have sent Riot Games like 4 bug reports, still no response. I didnt know where to go with this, but i guess some of you might have a solution/reason for this issue.
